The difference that matters

A canvas tent camper against a hard-sided A-frame. The Forest River Flagstaff Tent MAC 238MT opens to 23 feet 11 inches with tent-end beds on each side, a gaucho and a slide-out booth dinette, sleeping six. The Aliner Classic Rear Sofa/Mattress raises its hard walls in about 30 seconds and has two beds, a 46 by 76 front bed and a 60 by 76 rear sofa that folds flat.

Weight favors the Aliner: 1,725 lb dry with a 160 lb hitch, against 2,518 lb and 290 lb for the Flagstaff. At 64 inches closed it still fits in many garages. It also comes with more installed: a heat-pump air conditioner, an 18,000 BTU furnace, a water heater, a microwave, a 3.2 cu ft refrigerator, an 11-gallon fresh tank and an outside shower. The Flagstaff's 772 lb cargo capacity, two-burner range and electric brakes cover the basics, with a 125 W panel and 12 V fridge in an option package.

Families that need six beds have their answer in the Flagstaff. Couples who want hard walls against wind and weather, and a lighter tow, lean toward the Aliner.
