Bigfoot 25B21FB vs inTech O-V-R Expedition

Bigfoot · Travel Trailer

The difference that matters

Construction and purpose split these two 7,500 lb GVWR trailers. The Bigfoot 25B21FB is a two-piece molded fiberglass shell with R8 insulation, heated enclosed tanks and a front-bed couples layout, at 4,553 lb dry. The O-V-R Expedition is inTech's off-road trailer: a welded aluminum cage frame, 26 in ball height and an enclosed, ducted-heat underbelly, at 5,200 lb dry and sleeping up to five. Its 600 lb hitch is heavier than the Bigfoot's 490 lb.

Equipment differs too. The Bigfoot includes 400 W of solar and a 30,000 BTU furnace; A/C is optional. The inTech includes a 15,000 BTU ducted A/C, a 25,000 BTU furnace, a 10 cu ft 12 V fridge and a power awning, with solar and lithium in an optional Off-Grid Package. It also holds more water, 44/30/26 gal against 34/27/22, and its 2,300 lb cargo rating is generous.

At 8.8 ft tall against 10.5 ft, the Bigfoot is also much lower.

Bigfoot 25B21FB: Cold-weather campers traveling as a couple who want a low, insulated fiberglass trailer with solar already on the roof.
inTech O-V-R Expedition: A small family heading down rough forest roads who want ground clearance, A/C included and room for five.
