01 What makes it unique
The Salem Villa 40RLB leaves Forest River's factory at 11,604 lbs dry with 1,841 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 40-gallon fresh tank spends 332 lbs of the 1,841 lbs before anything else goes in.
Tongue weight is 1,445 lbs, 12% 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: 160 gallons of grey and black capacity against 40 gallons of fresh water, so fresh water runs out first (tank sizes by length).
Against the rest of the Salem Villa roster this is the 4th of 12 floorplans by dry weight, in a line that runs from 9,234 lbs to 14,404 lbs. It sits in the lighter third of the line.
Plan the tow on loaded weight, not the 11,604 lbs dry figure: half the published cargo capacity brings this plan to about 12,524 lbs. Forest River publishes no loaded rating for this line, so the ceiling is the one on the trailer’s own weight label (how to read trailer weights).
Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. No GVWR is published for this line, so dry plus cargo has no rating to check against. A missing row means Forest River does not publish that figure (how figures are verified).
Forest River's own description of this floorplan reads: “The 40RLB is an open floorplan that maximizes space for a residential cottage look and feel. The large king bedroom provides plenty of storage and washer/dryer hookup. The bathroom offers a walk-in shower with built-in seat, skylight, and linen cabinets. The island kitchen provides residential appliances and plenty of room for all the cooking essentials. Don’t forget the awesome view out the panoramic windows.” That is the factory's marketing copy rather than a specification, and nothing in it is treated as a verified field on this page - layout descriptions, sleeping arrangements and feature claims in factory copy are not carried into the spec table unless the factory also publishes them as specifications.
How the 40RLB differs from the other eleven Salem Villa floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 11,604 lb: fourth-lightest of twelve, between the 42DMS (11,484 lb) and the 42QBQ (12,029 lb).
- Tongue weight, 1,445 lb: fourth-lightest of twelve, between the 42QBQ (1,365 lb) and the 42DMS (1,475 lb).
- Cargo capacity, 1,841 lb: fifth-smallest of twelve, between the 42FLDL (1,511 lb) and the 44ZEN (1,891 lb).
- Grey tank, 120 gal: largest of twelve, level with the 40ZZZ; next are the 40FKP, 42DL and four others (80 gal).
- Tongue weight as a share of dry weight, 12.5%: sixth-smallest of twelve, between the 40FDEN (11.9%) and the 42ICE (12.7%).
- Length, 43 ft: sixth-shortest of twelve, between the 40FDEN (42 ft 5 in) and the 40FKP (43 ft 3 in).
- Exterior height, 12 ft 8 in: lowest of twelve, level with the 353FLFB, 40FDEN and two others; next is the 42DL (13 ft).
Next to the 42DMS, the nearest lighter floorplan by dry weight, the 40RLB is 120 lb heavier by dry weight, has 150 lb less cargo capacity, has a tongue weight 30 lb lighter, is 10 in shorter, has a grey tank 50 gal larger and has a black tank 40 gal smaller; the two publish the same exterior height and fresh tank.
Next to the 42QBQ, the nearest heavier floorplan by dry weight, the 40RLB is 425 lb lighter by dry weight, has 505 lb more cargo capacity, has a tongue weight 80 lb heavier, is 8 in longer, has a grey tank 40 gal larger and has a black tank 40 gal smaller; the two publish the same exterior height and fresh tank.

The 2027 model year, as Forest River lists it
Forest River’s own floorplan page lists the 2027 Salem Villa / Wildwood Lodge 40RLB with the figures below (read 22 Oct 2026). They are that year’s record. The specifications above are the 2026 record; the two are not merged, and neither fills a gap in the other. Every weight, dimension and tank figure in it matches the 2026 record above. Forest River publishes no GVWR for this floorplan, so none is shown and none is computed. Forest River’s 2027 roster now files the 40RLB under Dealer Stock Only rather than under a Salem Villa grouping; the figures below are what its own floorplan page prints.

03 The Salem Villa floorplan family
These are destination trailers - towed to a seasonal site, levelled, and largely left there - and the numbers only make sense read that way. Fourteen floorplans run 9,234 to 14,404 lb dry against cargo capacity of just 886 to 2,446 lb. On a touring trailer that ratio would be a warning; here it is the design, because the trailer is not being loaded for a trip. What it does mean is that the fit-out a seasonal site accumulates eats the margin quickly, and 886 lb is not much once a screen room, a grill and a season of furniture are aboard. All fourteen are bumper pull, with 1,260 to 1,855 lb on the tongue - for a tow most owners make twice a year, which is why so many of these are delivered rather than towed by the buyer. Forest River splits the roster into a standard group and a Grand group, and the split is real: the six Grand plans start at 12,209 lb dry where the six standard plans start at 9,234 lb. Fresh water is 39 to 40 gallons across the whole roster, which is a plumbed-site number rather than a boondocking one and tells you plainly what these are for.

|---|---|---|---|---|
| 353FLFB | 37' 9" | 9,234 | 2,301 | Salem Villa |

| 42ZEN | 44' 11" | 14,404 | 2,400 | Salem Grand Villa |
Forest River publishes this roster under four names on two factory line pages: Salem Villa and Salem Grand Villa on one, Wildwood Lodge and Wildwood Grand Lodge on the other. The two pages carry the same fourteen floorplan codes and the same specifications - 231 non-null published fields on each side, and the only differences across all fourteen plans are five floorplan description sentences that differ because each names its own badge. That is the same east/west twin naming already reflected in this reference's merged Salem and Wildwood hubs, so this line is catalogued once under all four names rather than twice. Forest River publishes no GVWR for any of the fourteen, so the loaded rating row reads not published rather than showing dry weight plus cargo capacity added together - that sum is an inference, not a rating, and a trailer's real limit can sit below it. Twelve plans are profiled; two, 42FK and 42VERANDA, are marked dealer stock only by the factory and are catalogued with their weights instead. Floorplan descriptions are published for 7 of the 14. Sleeping capacity, axle count, tire size and MSRP are not published in this channel.
04 Notes on this floorplan
What Forest River does not publish for this line
Sleeping capacity, axle count, tire size and MSRP are not in Forest River’s specification channel for Salem Villa, so this page does not publish them and does not estimate them (how figures are verified).
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and tongue weight for every Salem Villa floorplan and publishes no GVWR for any of them. The factory's own glossary defines cargo capacity as GVWR minus UVW, which means the rating can be worked out - and a figure you worked out is not a figure the manufacturer published, so this page does not print one. Use the weight label on the trailer itself, which every Forest River unit carries.
Weigh it before you tow it
Forest River calls its unloaded weight an estimated average for a standard build, and options and dealer add-ons change it, so weigh your own trailer loaded the way you travel (how figures are verified).
05 How it compares
11,484 lbs dry against this plan's 11,604 lbs, a difference of 120 lbs.
12,029 lbs dry, 425 lbs more than this plan, and 1,336 lbs of cargo capacity against this one's 1,841 lbs.
2,400 lbs of cargo capacity, the highest of the 12 Salem Villa floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 40-gallon fresh tank is about 332 lb of water, 18% of the 40RLB’s 1,841 lb cargo capacity, leaving 1,509 lb. Across 12 Salem Villa floorplans the water share runs 14% to 37%, and 4 give up more than this one. Nearest on that share: Salem Villa 44ZEN at 18% and Salem Villa 42FLDL at 22%.
07 Where this floorplan sits
Closest sibling: the Salem Villa 40FKP, nearest on the published figures. It differs on 5 of the 7 fields both publish (this plan first): length 43 ft 0 in vs 43 ft 3 in; dry weight 11,604 lb vs 12,269 lb; cargo capacity 1,841 lb vs 2,000 lb; hitch weight 1,445 lb vs 1,585 lb; grey tank 120 gal vs 80 gal. They match on fresh tank and black tank.
