A slide in camper will never be big enough for an extended trip.
I prefer a travel trailer, but no longer than a 24 foot bumper pull. If get you get one longer you will be limited to where you camp. Walk into campgrounds before you pull in or you might get stuck.
A boat will fit on a good 4x4, 1 ton pickup with a rack. With a long bed, a quad or something will fit.
You are not alone trying to figure this out.
Forget the boat and take up fly fishing.
