01 What makes it unique
The Prime Time Avenger 20RBS leaves Forest River's factory at 5,253 lbs dry with 2,297 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 42-gallon fresh tank spends 349 lbs of the 2,297 lbs before anything else goes in.
Tongue weight is 550 lbs, or 10% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.
Tank capacities are 42 gallons fresh, 30 grey and 30 black, 60 gallons of waste capacity against 42 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Forest River publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.
Against the rest of the Prime Time Avenger roster this is the 8th of 11 floorplans by dry weight, in a line that runs from 2,534 lbs to 7,393 lbs. It sits in the heavier third of the line. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.
A useful way to read these figures is to stop planning against the dry weight. Nobody tows a trailer at 5,253 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity and this plan is already near 6,401 lbs on the road. Because Forest River publishes no loaded rating for this line, the ceiling has to come from the trailer's own weight label rather than from this page, and the comparison you make against the tow vehicle should use the loaded figure.
Every number above was captured twice from Forest River and checked against itself before it was published. The line listing and the individual floorplan page are two separate factory renderings of the same trailer, and this plan's 4 shared figures agree exactly on both. There is no published GVWR on this line, so the usual arithmetic check - dry plus cargo equals the rating - has nothing to test against here. Where a figure is missing from this page it is because Forest River does not publish it in this channel, not because it was hard to find - and the row says so rather than being quietly dropped.
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. 20RBS is a Prime Time Avenger designation and this site does not decode it into a layout claim.
How the 20RBS differs from the other ten Prime Time Avenger floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.
- Tongue weight as a share of dry weight, 10.5%: smallest of eleven; next is the 17RDX (10.8%).
- Cargo capacity, 2,297 lb: third-largest of eleven, between the 16BHX (1,666 lb) and the 28QBS (2,427 lb).
- Dry weight, 5,253 lb: fourth-heaviest of eleven, between the 18DBS (3,939 lb) and the 25RKM (6,028 lb).
- Tongue weight, 550 lb: fourth-heaviest of eleven, between the 17DBX (515 lb) and the 25RKM (660 lb).
- Length, 25 ft 11 in: fourth-longest of eleven, between the 17RDX (23 ft 6 in) and the 25RKM (29 ft 11 in).
- Exterior height, 10 ft 8 in: shared with the 25RKM and 28QBS; of eleven, seven lower and one taller, nearest the 12RDX, 16BHX and three others (10 ft 4 in) and the 27TTI (11 ft 1 in).
Next to the 18DBS, the nearest lighter floorplan by dry weight, the 20RBS is 1,314 lb heavier by dry weight, has 1,336 lb more cargo capacity, has a tongue weight 50 lb heavier, is 2 ft 8 in longer, stands 4 in taller and has a fresh tank 1 gal larger; the two publish the same grey tank and black tank.
Next to the 25RKM, the nearest heavier floorplan by dry weight, the 20RBS is 775 lb lighter by dry weight, has 665 lb more cargo capacity, has a tongue weight 110 lb lighter, is 4 ft shorter, has a grey tank 4 gal smaller and has a black tank 38 gal smaller; the two publish the same exterior height and fresh tank.

03 The Prime Time Avenger floorplan family
Fifteen 2027 Prime Time Avenger floorplans with a full factory record, read from Forest River on 24 Oct 2026. They run 2,534 to 8,483 lb dry on lengths of 16 feet to 37 feet 5 inches, with hitch weights of 320 to 1,090 lb and cargo capacities of 961 to 2,732 lb. Forest River publishes no GVWR for these plans in this channel, so none is shown and none is computed.

|---|---|---|---|---|
| 12BHX | 16' 0" | 2,534 | 1,461 | Avenger LT |

Forest River's 2027 Prime Time Avenger roster, read 24 Oct 2026, lists fifteen floorplans. 16BHX, 18DBS, 20RBS, 27TTI are on this site for the first time; eleven already have their own page here, which keeps the record it was built from. 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 absent from Forest River's specification channel for Prime Time Avenger, so they are absent here. They are not estimated from the segment, not carried over from a sibling floorplan, and not taken from a dealer listing quoting itself. A tire size in particular is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
There is no factory GVWR for this trailer
Forest River publishes dry weight, cargo capacity and tongue weight for every Prime Time Avenger 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.
Awning size is not published for this floorplan
Forest River publishes an awning size for some Prime Time Avenger floorplans and not for this one. The row reads as unpublished rather than being filled from a neighbouring plan in the same roster.
Weigh it before you tow it
Every figure on this page is a factory publication for a standard build. Forest River's own footnote on unloaded weight calls it an estimated average based on a standard build with optional equipment, and options, dealer-installed accessories and the previous owner's additions all move it. The only weight that governs your towing decision is the one under your own trailer on a scale, loaded the way you actually travel.
05 How it compares
3,939 lbs dry against this plan's 5,253 lbs, a difference of 1,314 lbs. Same line, same factory channel, same model year - so the gap is a real one rather than a difference in how two brands measure.
5,863 lbs dry, 610 lbs more than this plan, and 1,757 lbs of cargo capacity against this one's 2,297 lbs. Stepping up a floorplan usually buys length before it buys payload.
2,497 lbs of cargo capacity, the highest of the 11 Prime Time Avenger 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 42-gallon fresh tank is about 349 lb of water, 15% of the 20RBS’s 2,297 lb cargo capacity, leaving 1,948 lb. Across 11 Prime Time Avenger floorplans the water share runs 14% to 35%, and 8 give up more than this one. Nearest on that share: Prime Time Avenger 28QBS at 14% and Prime Time Avenger 16BHX at 20%.
07 Where this floorplan sits
Closest sibling: the Prime Time Avenger 17DBX, nearest on the published figures. It differs on 5 of the 7 fields both publish (this plan first): length 25 ft 11 in vs 23 ft 2 in; dry weight 5,253 lb vs 3,649 lb; cargo capacity 2,297 lb vs 1,266 lb; hitch weight 550 lb vs 515 lb; fresh tank 42 gal vs 41 gal. They match on grey tank and black tank.

11 NHTSA safety record
NHTSA holds 9 recall campaigns and 6 owner complaints (model years 2005 on) against the Avenger line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
Too few reports to show a pattern. 6 complaints have been filed on this line — not enough to say what fails most often. They cover tires, equipment and structure.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Avenger line page.
