Will It Tow?
Fifth wheel · 18,000 lb GVWR · 15,139 lb dry · 3,015 lb dry hitch · 42.1 ft long
Out of 23 trucks, checked at the camper's full GVWR with about 820 lb in the truck: two adults, a dog, gear and the hitch. "Any build" means within every rating even on the version of that truck with the least payload.
Ratings come from manufacturer towing guides and spec sheets. These are planning estimates, not a safety guarantee. Your truck and camper stickers, your owner's manual and a scale always win.
