2026 Forest River Ozark1670RB

The Ozark 1670RB leaves Forest River's factory at 4,064 lbs dry, with a published GVWR of 5,550 lbs and 1,486 lbs of cargo capacity between the two. Cargo capacity is 27% of the loaded rating, and Forest River's own definition is worth reading before you plan against it: cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 39-gallon fresh tank spends 324 lbs of that 1,486 lbs before anything else is loaded.

Dry tongue weight is 450 lbs, or 11% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.

Tank capacities are 39 gallons fresh, 30 grey and 30 black, 60 gallons of waste capacity against 39 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 Ozark roster this is the 4th of 15 floorplans by dry weight, in a line that runs from 2,504 lbs to 7,648 lbs. It sits in the lighter 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 the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 4,064 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 4,807 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 5,550 lbs is a limit rather than a target.

Every number above was captured twice from Forest River and checked against itself before it was published. The line listing and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because Forest River does not publish it in this channel, 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. 1670RB is a Ozark designation and this site does not decode it into a layout claim.

Ozark is Forest River's entry-weight travel trailer, and the roster is unusual for how far down the scale it reaches: the smallest plan leaves the factory at just over 2,500 lb dry, which is genuinely inside the tow rating of a mid-size crossover rather than nominally inside it. The line splits four ways on the factory roster - single-axle, tandem-axle, limited-edition and toy hauler - and the toy haulers sit at the top of the weight range.

A full 39-gallon fresh tank is about 325 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 22% of the 1670RB’s 1,486 lb cargo capacity, leaving 1,161 lb. Across 13 Ozark floorplans the water share runs 10% to 45%, and 7 give up more than this one. Nearest on that share: Ozark 2430RBK at 21% and Ozark 1680BSK at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

Closest sibling: the Ozark 1680BSK, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 23 ft 1 in vs 23 ft 2 in; dry weight 4,064 lb vs 4,269 lb; GVWR 5,550 lb vs 5,655 lb; cargo capacity 1,486 lb vs 1,386 lb; dry hitch weight 450 lb vs 555 lb. They match on fresh tank, grey tank and black tank.

Either side of it by GVWR: Ozark 1620DBLE is 1,600 lb lighter (3,950 lb GVWR); Ozark 1680BSK is 105 lb heavier (5,655 lb GVWR).

All 13 Ozark floorplans: Ozark line hub.

Against the 1670RB: the Cherokee Wolf Pup 16FQW is 5 lb lighter and 1 ft shorter; the Cascade 17SCC is 10 lb lighter.

10 of the 18 fields this catalogue tracks are published for the 1670RB. Not published: interior height, sleeps, slide count, axle count, tire specification, awning, refrigerator, air conditioning.
