2026 Hideout178RB

The Hideout 178RB is a single-axle front-bedroom layout with a rear bath and a booth dinette — a 20-foot travel trailer aimed at couples and first-time buyers who want a light, simple two-person trailer. The rear bath and front bedroom give it a grown-up layout in one of the lightest trailers in the catalog.

It carries the single-axle Hideout build — an 8-foot-wide aluminum sidewall, an AlphaPly TPO roof under a lifetime warranty, Dura-floor decking and a single 3,500-pound axle, on a single axle. At 3,024 pounds dry against a 4,400-pound GVWR it leaves 1,376 pounds of cargo capacity, and the dry tongue weight is 400 pounds. A 3.3 cu ft refrigerator and 13.5K BTU air conditioning round out the equipment.

A figure worth stating plainly: Dry weight (3,024 lb) is confirmed from dealer listings; GVWR is derived as dry plus the RVUSA cargo capacity (1,376 lb = 4,400). As with every lightweight trailer, the published tongue weight is a pre-production dry estimate — once water, gear and passengers are aboard, real loaded tongue weight runs higher and lands on the tow vehicle's payload, so weigh the loaded trailer and match it to your truck honestly before relying on the brochure number. For couples and first-time buyers who want a light, simple two-person trailer, the 178RB is a well-targeted pick within the Keystone value stack.

Keystone's Hideout covers a dual-axle family line and a lighter single-axle line (filed by RVUSA as Hideout Mini, marketed for 2026 as Hideout Sport) for SUV towing. The plan on this page is highlighted; each profiled plan links to its own page. The full Hideout catalog runs to dozens of floorplans — the highest-demand layouts are detailed here and the rest are catalogued on the Hideout hub.

This floorplan carries its water comfortably. A full 21-gallon fresh tank is roughly 13% of the 1,376-pound cargo capacity, leaving the 178RB with a usable gear budget even when you tow full.

The published dry tongue weight of 400 pounds is 13% of the 3,024-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 4,400-pound GVWR the 178RB is towing 1,376 pounds more than its 3,024-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 21 gallons of fresh against 30 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by GVWR, the 178RB sits 2 of 10 in the Hideout line: 4,400 pounds against a line that runs from 4,350 to 7,700 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: Hideout 175BH is 50 pounds lighter at 4,350 lb GVWR; and Hideout 176BH is 45 pounds heavier at 4,445 lb GVWR.

Against the 178RB: the Zinger Lite Mini 18BH sleeps 2 more; the Flagstaff E-Pro E191FDT is 5 lb heavier and sleeps 1 fewer; the Rockwood Geo Pro G19FDT is 5 lb heavier and sleeps 1 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 Hideout floorplans profiled here run 3,020 to 6,205 pounds dry and 20 to 31 feet of exterior length across 10 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 Hideout line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 15 of them for the 178RB. 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: exterior width, interior height, tire specification. 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 (90%) 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.

How every figure here was sourced and checked is set out on the methodology page.
