Raptor toy haulers strike the perfect balance of residential comfort and flexibility to deliver no-limits adventure that evolves as you do. Luxurious Living Space Unlike a lot of travel trailers or fifth wheels, Raptor Toy Haulers bring a feeling of glamping to the outdoors. Whether you're in a campground or boondocking with a generator, you and your family will have everything you need to cook, rest, and sleep in comfort and style. We know this can mean a lot to keep the peace with family members or friends who aren't as ready to spend time in nature as others. The spacious master bathroom is a highlight, with two separate entries and a skylight in the single-piece shower. We especially appreciate the power vent and porcelain toilet with a foot pedal flush. In the kitchen, the Raptors also get high marks. We like the large stainless-steel sink and pull-out faucet along with the handsome cabinetry with shaker-style doors. Cook whatever you catch or kill (or buy from the grocery store) on the recessed three-burner range and 22-inch oven or 30-inch stainless steel convection microwave. Store leftovers in the large, 18-cubic-foot refrigerator.
