01 What makes it unique
The EVO 174DBLE has 706 lbs of cargo capacity between 3,229 lbs dry and its 3,935 lbs GVWR, 18% of that rating; filling its 39-gallon fresh tank at 8.3 lb a gallon uses 324 lbs of it (how to read trailer weights).
Tongue weight is 435 lbs, 13% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).
Off hookups: 60 gallons of grey and black capacity against 39 gallons of fresh water, so fresh water runs out first (tank sizes by length).
Against the rest of the EVO roster this is the 3rd of 18 floorplans by dry weight, in a line that runs from 2,504 lbs to 7,433 lbs. It sits in the lighter third of the line.
Plan the tow on loaded weight, not the 3,229 lbs dry figure: half the published cargo capacity brings this plan to about 3,582 lbs, and the published GVWR of 3,935 lbs is the limit (how to read trailer weights).
Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).
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. 174DBLE is a EVO designation and this site does not decode it into a layout claim.
How the 174DBLE differs from the other seventeen EVO floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity, 706 lb: smallest of eighteen; next is the 164FBLE (877 lb).
- Cargo capacity as a share of GVWR, 17.9%: smallest of eighteen; next is the 26ICE (19.2%).
- Dry weight, 3,229 lb: third-lightest of eighteen, between the 164FBLE (2,988 lb) and the 179DB (3,515 lb).
- GVWR, 3,935 lb: third-lowest of eighteen, between the 135ICE and 164FBLE (3,865 lb) and the 179DB (4,892 lb).
- Length, 21 ft 8 in: third-shortest of eighteen, between the 164FBLE (20 ft 2 in) and the 179DB (22 ft 5 in).
- Tongue weight, 435 lb: fourth-lightest of eighteen, between the 163RD (420 lb) and the 179DB (492 lb).
- Exterior height, 10 ft 3 in: shared with the 135ICE; of eighteen, two lower and fourteen taller, nearest the 164FBLE and 179DB (10 ft 2 in) and the 25ICE, 26ICE and two others (10 ft 4 in).
- Tongue weight as a share of dry weight, 13.5%: shared with the 260ICE; of eighteen, thirteen smaller and three larger, nearest the 2405BHX and 2480VBX (12.6%) and the 178BHS (13.6%).
- Grey tank, 30 gal: shared with the 135ICE, 164FBLE and 2750QBX; of eighteen, one smaller and thirteen larger, nearest the 179DB (27 gal) and the 178BHS and 2985VBX (32 gal).
- Fresh tank, 39 gal: smallest of eighteen, level with the 163RD, 164FBLE and four others; next are the 25ICE, 260ICE and 26ICE (40 gal).
- Black tank, 30 gal: shared with the 135ICE, 164FBLE and five others; of eighteen, four smaller and six larger, nearest the 163RD, 165VW and two others (27 gal) and the 2290ER, 2405BHX and two others (32 gal).
Next to the 164FBLE, the nearest lighter floorplan by dry weight, the 174DBLE is 241 lb heavier by dry weight, has a GVWR 70 lb higher, has 171 lb less cargo capacity, has a tongue weight 70 lb heavier, is 1 ft 6 in longer and stands 1 in taller; the two publish the same fresh tank, grey tank and black tank.
Next to the 179DB, the nearest heavier floorplan by dry weight, the 174DBLE is 286 lb lighter by dry weight, has a GVWR 957 lb lower, has 671 lb less cargo capacity, has a tongue weight 57 lb lighter, is 9 in shorter, stands 1 in taller, has a grey tank 3 gal larger and has a black tank 3 gal larger; the two publish the same fresh tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (3,935 lb) and the upper loaded tongue estimate (590 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.
03 The EVO floorplan family
EVO is not one roster but four, and the factory publishes them under separate headings: EVO, EVO Lites, EVO Selects and EVO Singles. That matters for anyone shopping by weight, because the sub-family a plan belongs to predicts its weight class more reliably than its floorplan number does - the Singles run single-axle and light, the base EVO group runs tandem-axle and heavier, and a buyer comparing two EVO plans by number alone can be a full tow class out.

EVO is published by Forest River as four sub-families - EVO, EVO Lites, EVO Selects and EVO Singles - across twenty-three floorplans for 2027. The sub-family each plan belongs to is shown in the table below because it is the strongest single predictor of weight class in this line. Forest River publishes dry weight, cargo capacity, tongue weight and the exterior dimensions for all twenty-three, and a GVWR for nineteen. Sleeping capacity, axle count, tire size and MSRP are not published in this channel.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are not in Forest River’s specification channel for EVO, so this page does not publish them and does not estimate them (how figures are verified).
Awning size is not published for this floorplan
Forest River publishes an awning size for some EVO 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
Forest River calls its unloaded weight an estimated average for a standard build, and options and dealer add-ons change it, so weigh your own trailer loaded the way you travel (how figures are verified).
05 How it compares
2,988 lbs dry against this plan's 3,229 lbs, a difference of 241 lbs.
3,515 lbs dry, 286 lbs more than this plan, and 1,377 lbs of cargo capacity against this one's 706 lbs.
3,082 lbs of cargo capacity, the highest of the 18 EVO 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
A full 39-gallon fresh tank is about 324 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 46% of the 174DBLE’s 706 lb cargo capacity, leaving 382 lb. Across 18 EVO floorplans the water share runs 11% to 46%, and this plan’s is the highest. Nearest on that share: EVO 164FBLE at 37%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the EVO 164FBLE, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 21 ft 8 in vs 20 ft 2 in; dry weight 3,229 lb vs 2,988 lb; GVWR 3,935 lb vs 3,865 lb; cargo capacity 706 lb vs 877 lb; hitch weight 435 lb vs 365 lb. They match on fresh tank, grey tank and black tank.

09 What this page publishes, and what it does not

11 NHTSA safety record
NHTSA holds 4 recall campaigns and 3 owner complaints (model years 2005 on) against the EVO line (a recall and a complaint are not the same thing).
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 suspension and structure.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the EVO line page.
