The Solitude sleeps up to 6, with enough room for a family.

At 19,000 lbs, this Solitude is a heavy unit that requires a one-ton truck or larger with a properly rated hitch and brake controller.

This Solitude is 42 feet long, placing it in the larger end of the Fifth Wheel category. Check campground length limits before booking, as some sites may not accommodate units over 40 feet.
