01 What makes it unique
The Arctic Wolf 3770SUITE leaves Forest River's factory at 10,893 lbs dry with 3,367 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 49-gallon fresh tank spends 407 lbs of the 3,367 lbs before anything else goes in.
Dry pin weight is 2,260 lbs, which is 21% of the dry weight. That figure lands on the truck's rear axle and comes straight off its payload rating - not its towing rating, which is the number most often quoted and the wrong one for this decision. Pin weight rises as the trailer is loaded, and a fifth wheel loaded toward its cargo capacity will put substantially more than 2,260 lbs over the bed. Read the payload figure on your own door sticker rather than a brochure maximum for the model.
Tank capacities are 49 gallons fresh, 70 grey and 70 black, 140 gallons of waste capacity against 49 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.
Against the rest of the Arctic Wolf roster this is the 8th of 9 floorplans by dry weight, in a line that runs from 7,583 lbs to 11,688 lbs. It sits in the heavier third of the line. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.
A useful way to read these figures is to stop planning against the dry weight. Nobody tows a trailer at 10,893 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 12,577 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.
Every number above was read from one factory document: Forest River's own 2022 brochure for this line, and each figure was read back against that document's text before it was published. This is a single-channel record rather than the two-rendering cross-check this site runs on factory web captures, and it is described that way rather than dressed up as more. The brochure publishes no GVWR for this line, so the loaded rating is shown as not published and is never computed from dry weight plus cargo capacity. Where a figure is missing from this page it is because the brochure does not publish it, not because it was hard to find - and the row says so rather than being quietly dropped.
Forest River publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 3770SUITE is a Arctic Wolf designation and this site does not decode it into a layout claim.

03 The Arctic Wolf floorplan family
Dry weight runs 7,583 to 11,688 lb across the nine plans and dry pin weight 1,140 to 2,260 lb. The pin figure is the one that decides whether a given truck can take the trailer, because a fifth-wheel pin load lands on the truck's payload rating rather than its towing rating - and a 2,260 lb pin will use most of a three-quarter-ton's payload before passengers and gear are counted. Cargo capacity runs 2,077 to 3,757 lb and moves against dry weight rather than with it: the lightest plan here carries the largest rating of the nine. Every plan holds 49 gallons of fresh water and 70 of grey; black is 35 gallons on seven plans and 70 on two. Travel length runs 30 ft 9 in to 43 ft 4 in and exterior height 12 ft 11 in to 13 ft 3 in - worth reading before a garage or a low bridge.
| Floorplan | Nominal | Sleeps | Notable | |
|---|---|---|---|---|
| 261RK | 30' 9" | 7,583 | 3,757 | Fifth Wheels |
| 291RL | 33' 6" | 8,358 | 3,097 | Fifth Wheels |

Arctic Wolf is the Cherokee family's full-size fifth wheel - a step above the travel trailers that carry the same Cherokee badging, and positioned in the value-mid part of Forest River's own fifth-wheel ladder rather than at the luxury end of it. The 2022 brochure publishes ten floorplans; the nine profiled here are the ones this site did not already carry from another model year. Every figure on this page is read from the 2022 document. Nothing is carried across from an adjacent model year, because this site measured elsewhere that two years of one floorplan can differ on half their published fields including tow-critical ones. Forest River publishes no GVWR for this line in this brochure, so the loaded rating is shown as not published. It is never computed from dry weight plus cargo capacity - that sum is what the trailer would weigh if you used every pound of its cargo rating, not a figure the manufacturer has certified the axles and frame against. These figures come from one factory document rather than from the two separate factory renderings this site cross-reads on Forest River's web channel, and every figure was read back against that document's own text before publication. Sleeping capacity, tire size, awning length and MSRP are not published in this brochure's specification table and are absent here rather than estimated.
04 What owners & reviewers report
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are absent from Forest River's specification channel for Arctic Wolf, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and dry pin weight for every Arctic Wolf floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Awning size is not published for this floorplan
Forest River publishes an awning size for some Arctic Wolf floorplans and not for this one. The row reads as unpublished rather than being filled from a neighbouring plan in the same roster.
Weigh it before you tow it
Every figure on this page is a factory publication for a standard build. Forest River's own footnote on unloaded weight calls it an estimated average based on a standard build with optional equipment, and options, dealer-installed accessories and the previous owner's additions all move it. The only weight that governs your towing decision is the one under your own trailer on a scale, loaded the way you actually travel.
05 How it compares
10,828 lbs dry against this plan's 10,893 lbs, a difference of 65 lbs. Same line, same factory channel, same model year - so the gap is a real one rather than a difference in how two brands measure.
11,688 lbs dry, 795 lbs more than this plan, and 2,392 lbs of cargo capacity against this one's 3,367 lbs. Stepping up a floorplan usually buys length before it buys payload.
3,757 lbs of cargo capacity, the highest of the 9 Arctic Wolf floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
This floorplan carries its water comfortably. A full 49-gallon fresh tank is roughly 12% of the 3,367-pound cargo capacity, leaving the 3770SUITE with a usable gear budget even when you tow full.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 3,367 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (49 gal × 8.34 lb) | −409 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 2,958 lb | 12% of this plan’s capacity is spent before a single bag is loaded. |
The published dry pin weight of 2,260 pounds is 21% of this floorplan’s 10,893-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.
Tank balance is generous here: 49 gallons of fresh against 70 grey and 70 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.
07 Where this floorplan sits
Ranked by dry weight, the 3770SUITE sits 13 of 15 in the Arctic Wolf line: 10,893 pounds against a line that runs from 7,583 to 12,563 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.
Either side of it in the same line: Arctic Wolf 3660SUITE is 65 pounds lighter at 10,828 lb dry; and Arctic Wolf 3990SUITE is 795 pounds heavier at 11,688 lb dry.
| Comparable fifth wheels | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 3770SUITE | — | 10,893 | — | 43 ft 2 in |
| Sandstorm 3300 | 16,555 | 10,879 | — | 36 ft 10 in |
| Wildcat 37PUB | 14,050 | 10,873 | 4 | 42 ft 9 in |
| Eagle 327CKTS | 13,250 | 10,920 | — | 37 ft 11 in |
| Blackthorn 2990MK | 14,180 | 10,864 | — | 35 ft 0 in |
| Rockwood Signature Fifth Wheels R372RL | — | 10,844 | — | 36 ft 10 in |
| Model Z 2680 | 13,995 | 10,978 | 5 | 29 ft 11 in |
Against the 3770SUITE: the Sandstorm 3300 is 14 lb lighter and 6 ft shorter; the Wildcat 37PUB is 20 lb lighter; the Eagle 327CKTS is 27 lb heavier and 5 ft shorter. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.
Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.
For scale, the Arctic Wolf floorplans profiled here run 7,583 to 12,563 pounds dry and 30 to 44 feet of exterior length across 15 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

08 Common questions about the 3770SUITE
How much can the 3770SUITE carry?
Cargo carrying capacity is 3,367 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring. Filling the 49-gallon fresh tank uses about 409 pounds of that.
What is the pin weight of the 3770SUITE?
The published dry pin weight is 2,260 pounds. It is measured empty; loaded, it runs higher, and it comes out of your tow vehicle’s payload rather than its tow rating.
What are the tank capacities on the 3770SUITE?
Fresh 49 gallons, grey 70 gallons, black 70 gallons. Tank sizes set how long the floorplan can sit away from hookups, and the smallest of the three is what ends the stay.
How long is the 3770SUITE?
Exterior length is 43' 2". Measure against your site length and your storage before committing — the exterior figure is the one that has to fit, and it includes the tongue or pin box.
Every figure in these answers is read from this page’s verified specification table. Where the manufacturer publishes nothing, the question is not answered rather than estimated.
09 What this page publishes, and what it does not
This catalog tracks 18 specification fields per floorplan. Named sources publish 9 of them for the 3770SUITE. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.
Not published for this floorplan: GVWR, interior height, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.
The completeness figure at the foot of this page (75%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.
How every figure here was sourced and checked is set out on the methodology page.
11 NHTSA safety record
This floorplan belongs to the Arctic Wolf line, and NHTSA holds 2 recall campaigns and 3 owner complaints against that line. They are separate records and are not added together — a recall is a manufacturer-confirmed defect with a remedy; a complaint is one owner’s account, which NHTSA does not verify.
Too few reports to show a pattern. 3 complaints have been filed on this line — not enough to say what fails most often. They cover structure and wheels.
Recall coverage is not complete — our harvest of NHTSA’s recall API ran 1,556 queries, of which 0 failed and 242 returned an explicit zero. A line can still be under-reported where NHTSA files a roster under a parent name, or where a match rests on the wording of the recall rather than its model field. Complaints come from the complete bulk file but are unverified and self-selected: a high count tracks how many units a line sold at least as much as how well it was built. Check a specific VIN at NHTSA before you buy. Full tables are on the Arctic Wolf line page.
