2026 Forest River Puma Tracks / Solaire237RK

The Puma Tracks 237RK has 1,587 lbs of cargo capacity between 4,918 lbs dry and its 6,505 lbs GVWR, 24% of that rating; filling its 42-gallon fresh tank at 8.3 lb a gallon uses 349 lbs of it (how to read trailer weights).

Tongue weight is 670 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: 106 gallons of grey and black capacity against 42 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Puma Tracks roster this is the 3rd of 14 floorplans by dry weight, in a line that runs from 4,728 lbs to 8,298 lbs. It sits in the lighter third of the line.

Plan the tow on loaded weight, not the 4,918 lbs dry figure: half the published cargo capacity brings this plan to about 5,712 lbs, and the published GVWR of 6,505 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. 237RK is a Puma Tracks designation and this site does not decode it into a layout claim.

How the 237RK differs from the other thirteen Puma Tracks floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 4,918 lb: third-lightest of fourteen, between the 232UD (4,858 lb) and the 2420RBS (5,328 lb).
• GVWR, 6,505 lb: third-lowest of fourteen, between the 232UD (6,440 lb) and the 2420RBS (6,903 lb).
• Cargo capacity as a share of GVWR, 24.4%: third-largest of fourteen, between the 2420RBS and 3150TBSS (22.8%) and the 232UD (24.6%).
• Tongue weight as a share of dry weight, 13.6%: largest of fourteen, level with the 3070RKLS; next is the 3060RKTS (13.5%).
• Length, 25 ft 9 in: shortest of fourteen, level with the 232UD; next is the 235BH (25 ft 11 in).
• Cargo capacity, 1,587 lb: sixth-smallest of fourteen, between the 235BH (1,585 lb) and the 2430BHS (1,596 lb).
• Tongue weight, 670 lb: sixth-lightest of fourteen, between the 2750BHS (650 lb) and the 2580RBSS and 302BHS (725 lb).
• Exterior height, 10 ft 10 in: lowest of fourteen, level with the 232UD, 235BH and two others; next are the 2420RBS, 2430BHS and seven others (11 ft 1 in).
• Grey tank, 76 gal: shared with the 3150TBSS and 3300FLBS; of fourteen, eight smaller and three larger, nearest the 2420RBS, 2580RBSS and 3200TSBH (68 gal) and the 3060RKTS, 3070RKLS and 3380RLBT (106 gal).
• Black tank, 30 gal: smallest of fourteen, level with the 232UD, 235BH and three others; next are the 2420RBS, 2580RBSS and six others (38 gal).

Next to the 232UD, the nearest lighter floorplan by dry weight, the 237RK is 60 lb heavier by dry weight, has a GVWR 65 lb higher, has 5 lb more cargo capacity, has a tongue weight 80 lb heavier and has a grey tank 16 gal larger; the two publish the same length, exterior height, fresh tank and black tank.

Next to the 2420RBS, the nearest heavier floorplan by dry weight, the 237RK is 410 lb lighter by dry weight, has a GVWR 398 lb lower, has 12 lb more cargo capacity, has a tongue weight 35 lb heavier, is 2 ft 2 in shorter, stands 3 in lower, has a grey tank 8 gal larger and has a black tank 8 gal smaller; the two publish the same fresh tank.

Tracks sits above Camping Edition and below the destination and fifth-wheel tiers of the Puma range. Dry weight runs 4,728 to 8,298 lbs with hitch weights from 585 to 1,080 lbs, and hitch weight is the figure that decides whether a given truck copes: it comes straight off the tow vehicle's payload before passengers and gear. Every plan in the class publishes a GVWR and every one of them ties out against its own unloaded weight and cargo capacity, which is not true of every Puma tier.

A full 42-gallon fresh tank is about 349 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 22% of the 237RK’s 1,587 lb cargo capacity, leaving 1,238 lb. Across 14 Puma Tracks floorplans the water share runs 18% to 28%, and 5 give up more than this one. Nearest on that share: Puma Tracks 2430BHS at 22% and Puma Tracks 235BH at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
