There are a number of ultra-light campers with positive ratings, including the Airstream Sport, Cruiser RV, Palomino Palomini 150RBS light weight travel trailer and the Bigfoot RV. Ultra-light campers are generally pulled behind a vehicle and are smaller versions of full-sized campers.
The Airstream Sport trailer has received positive reviews from trailerlife.com. They note that the trailer manages to get a lot of function into a small space. It is also light enough to be towed by a small pickup truck or SUV. The trailer has Airstream's classic silver rounded shape.
Campinglife.com spotlights the Cruiser RV for its 37-inch deep and 11-foot-6-inch long slideout section. This feature adds a lot of interior room to the RV.
Roamingtimes.com highlights the Palomino Palomini. The site likes the RV's bed and shower placement, its walkable roof and large amount of storage space, among other features. As for the Bigfoot RV, Trailerlife.com notes that it is larger than many ultra-lightweight campers. The camper is built to be used year-round with thermopane windows, ducted furnaces and an air conditioning system.
