Airstream Caravel 22FB vs Bigfoot 25B21FB
The difference that matters
Two 21 to 22 ft front-bed trailers built in very different ways. The Caravel is a riveted aluminum Airstream at 4,175 lb dry with a 5,000 lb GVWR. The Bigfoot is a two-piece molded fiberglass shell with R8 insulation, 4,553 lb dry and rated to 7,500 lb, so it has far more headroom for gear and full tanks. Its hitch weight is slightly lower, 490 lb against 525 lb.
The Bigfoot is built for cold weather and boondocking: heated, enclosed tanks, a 30,000 BTU furnace, 400 W of solar and bigger tanks at 34/27/22 gal against 23/30/17. A/C is an option on it. The Caravel ships with more electrical kit, including a 2.5 kWh heated lithium bank, a 2,000 W inverter and a ducted heat-pump A/C, plus 200 W of solar and a three-burner stove with oven.
The Bigfoot also stands 8.8 ft tall against 9.4 ft.
