Not sure if you mean to tow in tandum or simply to load a boat on top of the camper - if that's what you meant, should be no problem providing it's not too big & heavy! I tote canoes and the pic I enclosed shows a Raddison "canoe boat" ... my main fishing boat. Very light aluminum, easy to carry, load and unload. In this case use those foam blocks that fit over the gunnel's of the boat ... but make sure they rest on the far edges of the roof ... right where the roof curves down, which is the strong part of the roof.

The good things about the foam blocks is they can be used for carrying the boat with other vehicles, too. The bad thing about them is you have to be careful loading the boat that you don't bang a dent in the roof (pup has an aluminum roof). A roof top carrier might be better for wear & tear on the roof.

Here's the little Starcraft loaded, ready to go on a fishing trip and ready to be hitched up ~
