2026 Forest River Columbus / Puma Mesa383RLH

The Columbus 383RLH has 3,026 lbs of cargo capacity between 13,609 lbs dry and its 16,635 lbs GVWR, 18% of that rating; filling its 75-gallon fresh tank at 8.3 lb a gallon uses 622 lbs of it (how to read trailer weights).

Pin weight is 2,635 lbs, 19% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 149 gallons of grey and black capacity against 75 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Columbus roster this is the 3rd of 8 floorplans by dry weight, in a line that runs from 10,464 lbs to 14,664 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 13,609 lbs dry figure: half the published cargo capacity brings this plan to about 15,122 lbs, and the published GVWR of 16,635 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. 383RLH is a Columbus designation and this site does not decode it into a layout claim.

How the 383RLH differs from the other seven Columbus floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Cargo capacity, 3,026 lb: largest of eight; next is the 384RKH (2,876 lb).
• Pin weight as a share of dry weight, 19.4%: second-largest of eight, between the 379MBL (19%) and the 384RKH (19.5%).
• Dry weight, 13,609 lb: third-lightest of eight, between the 360FK (11,489 lb) and the 384RKH (13,814 lb).
• Cargo capacity as a share of GVWR, 18.2%: third-largest of eight, between the 384RKH (17.2%) and the 340RG (18.7%).
• Length, 41 ft 5 in: third-shortest of eight, between the 360FK (36 ft 3 in) and the 377DS, 379MBL and 389FLH (42 ft 7 in).
• GVWR, 16,635 lb: fourth-highest of eight, between the 389FLH (16,555 lb) and the 388FKH (16,685 lb).
• Pin weight, 2,635 lb: fourth-heaviest of eight, between the 389FLH (2,555 lb) and the 388FKH (2,685 lb).
• Grey tank, 78 gal: smallest of eight, level with the 340RG, 360FK and 379MBL; next are the 388FKH and 389FLH (110 gal).
• Black tank, 71 gal: shared with the 384RKH; of eight, four smaller and two larger, nearest the 340RG, 360FK and two others (39 gal) and the 377DS and 388FKH (78 gal).

Next to the 360FK (2027 page), the nearest lighter floorplan by dry weight, the 383RLH is 2,120 lb heavier by dry weight, has a GVWR 2,460 lb higher, has 340 lb more cargo capacity, has a pin weight 460 lb heavier, is 5 ft 2 in longer and has a black tank 32 gal larger; the two publish the same exterior height, fresh tank and grey tank.

Next to the 384RKH, the nearest heavier floorplan by dry weight, the 383RLH is 205 lb lighter by dry weight, has a GVWR 55 lb lower, has 150 lb more cargo capacity, has a pin weight 55 lb lighter, is 1 ft 7 in shorter and has a grey tank 39 gal smaller; the two publish the same exterior height, fresh tank and black tank.

Columbus is a tight roster of six large fifth wheels and the numbers barely move across it: 13,609 to 14,664 lb dry over lengths of 41 feet 5 inches to 43 feet. What does move is cargo capacity, 2,026 to 3,026 lb - a thousand-pound spread on trailers within a thousand pounds of each other dry, so the useful comparison inside this line is payload rather than size. Pin weight runs 2,480 to 2,785 lb, and every plan ties out exactly against its published GVWR.

A full 75-gallon fresh tank is about 622 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 21% of the 383RLH’s 3,026 lb cargo capacity, leaving 2,404 lb. Across 8 Columbus floorplans the water share runs 21% to 31%, and this plan’s is the lowest. Nearest on that share: Columbus 384RKH at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
