01 What makes it unique
Though nearly identical in length to the 27FB, the 28RB feels like a different trailer. The main door opens at the front into a spacious living area with an L-shaped lounge that doubles as sleeping space, while a queen (or twins) sits at the rear under panoramic windows for exceptional morning views. A convertible dinette across from the galley adds more sleeping room, and the bathroom and shower split across the aisle. It sleeps six.
It carries the full International package — the tankless on-demand water heater, powered ZipDee awning, standard rearview camera, DuPont Corian counters, Ultraleather seating, and the coastal decor — but the rear-bed layout means it does not offer the rear hatch or the front bunk, which are front-bedroom features. A second air conditioner is available.
At 5,900 pounds dry, a 7,600-pound GVWR, and the line's strong 1,700-pound cargo rating, it tows much like the 27FB. Starting MSRP is $142,400, matched to the 27FB — the choice between them is purely layout: front bed and a rear hatch, or a rear bed and a front lounge.

Loaded weight budget
Size, drawn to scale
These graphics are generated from the same verified record that builds the table above, and are published under this site’s own licence — nothing here is traced from, or derived from, a manufacturer drawing or photo. Where a figure is not published for this plan, the graphic that would need it is omitted rather than estimated. The full record is in the published dataset.
What it takes to tow this
Built from this floorplan’s verified weights. We publish the trailer side only.
We do not publish tow ratings for specific trucks. A single model can vary by thousands of pounds depending on engine, axle ratio, cab, drivetrain and package — the only authoritative figure is the one on your own door jamb. Loaded tongue percentages are industry convention for travel trailers (10–15% of loaded weight), not a measurement of this unit. Hitch classes are not used here as a rating: SAE J684 covers trailers to 10,000 lb GVWR and does not define Class V, and capacity boundaries differ between manufacturers — read the rating stamped on your hitch. On this plan the convention band’s low end fell below the published dry figure, so the range starts at the published dry weight instead — loaded is never lighter than dry.
03 International floorplan family
The current International line — five dual-axle floorplans, each offered in queen or twin bedroom configurations. The 28RB on this page is highlighted; each other plan links to its own profile.
| Floorplan | Nominal | Bedroom | Sleeps | Notable |
|---|---|---|---|---|
| 23FB | 23 ft | Front | 6 | Entry; rear full-width bath; 8' body |
| 25FB | 25 ft | Front | 6 | Wider body; rear hatch + bunk options |
| 27FB | 27 ft | Front | 6 | Most popular; biggest galley/storage |
| 28RB | 28 ft | Rear | 6 | Front lounge entry; rear bed |
| 30RB | 30 ft | Rear | 6 | Largest; most capacity; 50-amp |
The optional rear hatch and front cross-bunk are available only on the 25FB and 27FB. The International shares its floorplans with the Flying Cloud but adds elevated coastal design, a tankless water heater, and powered features.
04 What owners & reviewers report
Rear bed, front lounge
Entry opens into the living space; the bedroom sits at the rear under panoramic windows — a calmer, residential feel.
No rear hatch or bunk
Those are front-bedroom options; the 28RB instead offers the rear-bed layout and front lounge.
Signature tankless water heater
Unlike the Flying Cloud's tank-style heater, the International uses an on-demand tankless LP water heater — continuous hot water without a reservoir.
Most cargo of the mid-line
1,700 lb net against a 7,600-lb GVWR edges out the 27FB on payload.
05 How it compares
A shorter, lighter front-bed plan with the rear-hatch option.
A larger rear-bed layout with more capacity and 50-amp service.
The same rear-bed plan in neutral decor with manual hardware, for notably less.
06 Loading it for a trip
Cargo capacity on the International 28RB is 1,700 pounds — the entire budget for gear, water, propane, batteries and everything else you put aboard.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 1,700 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Per sleeping position, water aboard | 283 lb | A rough share of what is left across the 6 berths this plan sleeps. |
The published dry tongue weight of 860 pounds is 15% of the 5,900-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.
Nothing above changes the ceiling. Loaded to its 7,600-pound GVWR the International 28RB is towing 1,700 pounds more than its 5,900-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.
07 Where this floorplan sits
Ranked by GVWR, the International 28RB sits 4 of 5 in the International line: 7,600 pounds against a line that runs from 6,000 to 8,800 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.
Either side of it in the same line: International 27FB matches it exactly at 7,600 lb GVWR; and International 30RB is 1,200 pounds heavier at 8,800 lb GVWR.
1 other International plan shares this floorplan’s 7,600 lb GVWR, so the ranking above separates plans that tow to the same ceiling. On a shared chassis the figure that actually differs between them is cargo capacity and where the weight sits, not the rating.
| Comparable travel trailers | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| International 28RB | 7,600 | 5,900 | 6 | 28 ft 2 in |
| Coachmen Apex Ultra-Lite 242BARV | 7,600 | 5,772 | 4 | 28 ft 10 in |
| Campsite Ultra 19KB | 7,600 | 5,158 | — | 22 ft 4 in |
| Classic Frank Lloyd Wright Usonian LE 28RB | 7,600 | 6,800 | 4 | 28 ft 2 in |
| Flying Cloud 27FB | 7,600 | 5,950 | 5 | 28 ft 2 in |
| Coachmen Freedom Express Ultra Lite 22MLS | 7,600 | 5,602 | 4 | 26 ft 10 in |
| Globetrotter 27FB | 7,600 | 6,258 | 6 | 28 ft 2 in |
Against the International 28RB: the Coachmen Apex Ultra-Lite 242BARV sleeps 2 fewer; the Campsite Ultra 19KB is 6 ft shorter; the Classic Frank Lloyd Wright Usonian LE 28RB sleeps 2 fewer. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.
Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.
For scale, the International floorplans profiled here run 5,100 to 6,600 pounds dry and 24 to 31 feet of exterior length across 5 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.
Every profiled floorplan in this line, with the full weight table, is on the International line hub.
08 Common questions about the International 28RB
How much does the International 28RB weigh?
It leaves the factory at 5,900 pounds dry, and its manufacturer-set loaded ceiling (GVWR) is 7,600 pounds. Real towing weight lands between the two and depends entirely on what you load. Use the GVWR when matching a tow vehicle; the dry figure is only useful for comparing floorplans against each other.
How much can the International 28RB carry?
Cargo carrying capacity is 1,700 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring.
What is the tongue weight of the International 28RB?
The published dry tongue weight is 860 pounds. It is measured empty; loaded, it runs higher, and it comes out of your tow vehicle’s payload rather than its tow rating.
What size tow vehicle does the International 28RB need?
Your vehicle needs a tow rating of at least 7,600 pounds — this floorplan’s GVWR — and enough payload left over for the hitch load, passengers and anything in the bed. This site does not publish tow ratings for specific vehicles, because one truck model varies by thousands of pounds across engine, axle ratio, cab and package. The figure that governs is the payload sticker on your own door jamb.
How many people does the International 28RB sleep?
It is rated to sleep 6. Rated sleeping positions include convertible furniture, so count the beds against how you actually travel rather than against the number.
How long is the International 28RB?
Exterior length is 28 ft 2 in. Measure against your site length and your storage before committing — the exterior figure is the one that has to fit, and it includes the tongue or pin box.
Every figure in these answers is read from this page’s verified specification table. Where the manufacturer publishes nothing, the question is not answered rather than estimated.
09 What this page publishes, and what it does not
This catalog tracks 18 specification fields per floorplan. Named sources publish 14 of them for the International 28RB. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.
Not published for this floorplan: fresh tank, grey tank, black tank, slide count. If you find one of these in a manufacturer document for this plan, it belongs on this page.
The completeness figure at the foot of this page (85%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.
Values on this page carrying an asterisk were derived by arithmetic from published figures, or come from a single source, rather than being printed directly by the manufacturer. The flag travels with the number into the downloadable spec sheet.
How every figure here was sourced and checked is set out on the methodology page.
11 NHTSA safety record
This floorplan belongs to the International line, and NHTSA holds 18 recall campaigns and 22 owner complaints against that line. They are separate records and are not added together — a recall is a manufacturer-confirmed defect with a remedy; a complaint is one owner’s account, which NHTSA does not verify.
What to look at on a used one. Across the 22 complaints filed on this line the most-reported components are structure (41%), unknown or other (18%) and tires (9%). That is where owners of this family have had trouble, so it is where an inspection is worth the time.
Reports that name the 28RB
1 of those record name this floorplan specifically rather than the line as a whole.
| Type | Date | Reference | What it says |
|---|---|---|---|
| Recall | 12 May 2021 | 21V345000 | A draft can cause the flame to enter the non-sealed cabinet, increasing the risk of a fire. |
Recall coverage is not complete — our harvest of NHTSA’s recall API ran 1,556 queries, of which 0 failed and 242 returned an explicit zero. A line can still be under-reported where NHTSA files a roster under a parent name, or where a match rests on the wording of the recall rather than its model field. Complaints come from the complete bulk file but are unverified and self-selected: a high count tracks how many units a line sold at least as much as how well it was built. Check a specific VIN at NHTSA before you buy. Full tables are on the International line page.
