2026 Forest River EVO179DB

The EVO 179DB has 1,377 lbs of cargo capacity between 3,515 lbs dry and its 4,892 lbs GVWR, 28% 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 492 lbs, 14% 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: 54 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 4th 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 3,515 lbs dry figure: half the published cargo capacity brings this plan to about 4,203 lbs, and the published GVWR of 4,892 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. 179DB is a EVO designation and this site does not decode it into a layout claim.

How the 179DB differs from the other seventeen EVO floorplans. Most distinctive first. How these ranks are worked out.

• Grey tank, 27 gal: smallest of eighteen; next are the 135ICE, 164FBLE and two others (30 gal).
• Tongue weight as a share of dry weight, 14%: second-largest of eighteen, between the 178BHS (13.6%) and the 135ICE (14.6%).
• Dry weight, 3,515 lb: fourth-lightest of eighteen, between the 174DBLE (3,229 lb) and the 178BHS (4,182 lb).
• GVWR, 4,892 lb: fourth-lowest of eighteen, between the 174DBLE (3,935 lb) and the 163RD (5,520 lb).
• Length, 22 ft 5 in: fourth-shortest of eighteen, between the 174DBLE (21 ft 8 in) and the 178BHS (22 ft 11 in).
• Tongue weight, 492 lb: fifth-lightest of eighteen, between the 174DBLE (435 lb) and the 233RBLE (520 lb).
• Exterior height, 10 ft 2 in: lowest of eighteen, level with the 164FBLE; next are the 135ICE and 174DBLE (10 ft 3 in).
• Cargo capacity, 1,377 lb: sixth-smallest of eighteen, between the 135ICE (1,361 lb) and the 178BHS (1,488 lb).
• Cargo capacity as a share of GVWR, 28.1%: sixth-largest of eighteen, between the 178BHS (26.2%) and the 2480VBX (28.2%).
• Black tank, 27 gal: smallest of eighteen, level with the 163RD, 165VW and 178BHS; next are the 135ICE, 164FBLE and six others (30 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).

Next to the 174DBLE, the nearest lighter floorplan by dry weight, the 179DB is 286 lb heavier by dry weight, has a GVWR 957 lb higher, has 671 lb more cargo capacity, has a tongue weight 57 lb heavier, is 9 in longer, stands 1 in lower, has a grey tank 3 gal smaller and has a black tank 3 gal smaller; the two publish the same fresh tank.

Next to the 178BHS, the nearest heavier floorplan by dry weight, the 179DB is 667 lb lighter by dry weight, has a GVWR 778 lb lower, has 111 lb less cargo capacity, has a tongue weight 78 lb lighter, is 6 in shorter, stands 6 in lower and has a grey tank 5 gal smaller; the two publish the same fresh tank and black tank.

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.

A full 39-gallon fresh tank is about 324 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 24% of the 179DB’s 1,377 lb cargo capacity, leaving 1,053 lb. Across 18 EVO floorplans the water share runs 11% to 46%, and 5 give up more than this one. Nearest on that share: EVO 2920VB at 23% and EVO 163RD at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
