2026 Forest River Ozark1670RB

The Ozark 1670RB has 1,486 lbs of cargo capacity between 4,064 lbs dry and its 5,550 lbs GVWR, 27% 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 450 lbs, 11% 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 Ozark roster this is the 4th of 13 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.

Plan the tow on loaded weight, not the 4,064 lbs dry figure: half the published cargo capacity brings this plan to about 4,807 lbs, and the published GVWR of 5,550 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. 1670RB is a Ozark designation and this site does not decode it into a layout claim.

How the 1670RB differs from the other twelve Ozark floorplans. Most distinctive first. How these ranks are worked out.

• Tongue weight as a share of dry weight, 11.1%: second-smallest of thirteen, between the 2690BHK (10.9%) and the 2300RBLE (11.4%).

• Exterior height, 10 ft 6 in: fifth-lowest of thirteen, between the 1610FBLE (10 ft 4 in) and the 2300RBLE and 2690BHK (11 ft).

Next to the 1620DBLE, the nearest lighter floorplan by dry weight, the 1670RB is 840 lb heavier by dry weight, has a GVWR 1,600 lb higher, has 760 lb more cargo capacity, is 1 ft 7 in longer and stands 4 in taller; the two publish the same tongue weight, fresh tank, grey tank and black tank.

Next to the 1680BSK, the nearest heavier floorplan by dry weight, the 1670RB is 205 lb lighter by dry weight, has a GVWR 105 lb lower, has 100 lb more cargo capacity, has a tongue weight 105 lb lighter, is 1 in shorter and stands 4 in taller; the two publish the same fresh tank, grey tank and black tank.

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. 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 324 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 1,162 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).
