2026 Forest River Puma Camping Edition121RKCE

The Puma Camping Edition 121RKCE has 1,176 lbs of cargo capacity between 2,664 lbs dry and its 3,840 lbs GVWR, 31% of that rating; filling its 34-gallon fresh tank at 8.3 lb a gallon uses 282 lbs of it (how to read trailer weights).

Tongue weight is 340 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 34 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Puma Camping Edition roster this is the 6th of 30 floorplans by dry weight, in a line that runs from 2,295 lbs to 7,018 lbs. It sits in the lighter third of the line.

Plan the tow on loaded weight, not the 2,664 lbs dry figure: half the published cargo capacity brings this plan to about 3,252 lbs, and the published GVWR of 3,840 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. 121RKCE is a Puma Camping Edition designation and this site does not decode it into a layout claim.

How the 121RKCE differs from the other 29 Puma Camping Edition floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

Next to the 120RKCE, the nearest lighter floorplan by dry weight, the 121RKCE is 50 lb heavier by dry weight, has a GVWR 20 lb lower, has 70 lb less cargo capacity, has a tongue weight 20 lb lighter and stands 2 in taller; the two publish the same length, fresh tank, grey tank and black tank.

Next to the 122BHCE, the floorplan with the same dry weight, the 121RKCE has a GVWR 25 lb lower, has 24 lb less cargo capacity and has a tongue weight 40 lb lighter; the two publish the same dry weight, length, exterior height, fresh tank, grey tank and black tank.

Next to the 123RDCE, the nearest heavier floorplan by dry weight, the 121RKCE is 20 lb lighter by dry weight, has a GVWR 25 lb lower, has 4 lb less cargo capacity and has a tongue weight 25 lb lighter; the two publish the same length, exterior height, fresh tank, grey tank and black tank.

Camping Edition is where Puma starts, and the range is wide enough that the badge on the side tells you very little on its own. The lightest plans here are single-axle trailers under 2,700 lbs dry; the heaviest are past 7,000 lbs dry. Cargo capacity runs 671 to 1,592 lbs and does not track length in the way buyers expect, so the plan that fits the family may not be the plan that carries their gear. Forest River publishes a GVWR for every plan in this class, which is the number to tow against.

A full 34-gallon fresh tank is about 282 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 24% of the 121RKCE’s 1,176 lb cargo capacity, leaving 894 lb. Across 30 Puma Camping Edition floorplans the water share runs 19% to 42%, and 4 give up more than this one. Nearest on that share: Puma Camping Edition 123RDCE at 24% and Puma Camping Edition 17BUNK at 25%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
