2026 E-Pro E171SLE

The Flagstaff E-Pro E171SLE is the only LE plan with a slide-out, which makes it one of the lightest slide-equipped trailers anywhere. Inside, a true front queen bed with overhead storage and wardrobes gives a proper bedroom, a jackknife sofa with a 30-by-15 swing table on the slide widens the living space at camp, and a kitchen with a two-burner cooktop, a convection microwave and a functional sink handles meals. A rear bathroom with a spacious rectangular shower and a porcelain toilet completes the layout — a genuine dry bath. Nominal capacity is two — a true couples’ coach that adds slide-out living space without giving up the easy tow weight of the LE line.

At 2,949 pounds unloaded and 20 feet, the E171SLE is an easy tow for mid-size SUVs and capable crossovers — strikingly light for a trailer with both a real queen bed and a slide; its 1,396-pound cargo capacity is generous, giving a couple real loading margin. Forest River does not print a GVWR on the factory detail page, so it is derived as unloaded weight plus cargo capacity, landing at 4,345 pounds. As an LE plan it ships the cost-friendly LE Package: Dexter leaf-spring E-Z Lube axles, a single battery and a single 20-pound LP tank, a 10K roof A/C, a power awning, a 20,000-BTU furnace, a 6-gallon water heater, framed windows and a roof-solar prep with a side port. Tanks are a balanced 31-gallon fresh, 27-gallon grey and 27-gallon black.

Construction is the E-Pro laminate recipe — complete composite Azdel walls over a 6-sided full-aluminum cage, a vacuum-laminated fiberglass roof and aluminum floor joists — the same construction tier as Forest River’s r·pod and No Boundaries and a step above the metal-sided value lines. E-Pro is badge-engineered with the Rockwood Geo Pro. For a couple who wants a real front queen bed and slide-out living space — not a convertible dinette — in the lightest, most affordable composite trailer that offers both, the E171SLE is the value couples’ plan with a slide.

Forest River’s Flagstaff E-Pro (badge-engineered as the Rockwood Geo Pro) is an off-grid, ultra-light travel-trailer line built “incredibly lightweight” to tow behind fuel-efficient crossovers and smaller SUVs. The E171SLE on this page is highlighted; the other profiled plans link to their own pages. Profiled here are breadth-spanning floorplans — from the sub-1,800-pound LE micro-trailer to the dual-axle family bunkhouse — with the rest of the roster catalogued on the line hub and profiled in demand order. Every E-Pro plan is built on a 6-sided aluminum cage with Azdel composite walls and a vacuum-laminated roof, rides on bigger off-road tires, and ships with a standard roof-solar prep, a 12V refrigerator and a 20,000-BTU furnace for boondocking-ready, extended-season camping.
