Nope, there isnt. They pop up on Spokane craigslist every now and then. I believe they have a welded aluminum frame.

Owner Dave Kirk custom builds ‘hi-n-low’ Roamin’ Chariot campers and canopies at his Spokane Valley (Wash.) location.
Perfect for the outdoors person, these neat, light-weight campers weight around 500 pounds for a compact truck and 600 pounds for a full-size truck.
I’ve looked inside one of these tightly crafted campers, and while sparse (how much room do you need for a weekend fishing) they do come standard with a dinette table, bed slide and mattress pads. There is a long list of options.
Cost for a Full Size, short or long bed is $5,900
Long Compact will run $5,500
Short Compact is $5,200
Dave says he could build one of these beauties for you in two weeks. Call him at (509) 927-8897 or Cell: (509) 209-1502 (Verizon)
