I know this a little far fetched and would take some serious engineering.
So many people on this forum have unlimited talent im surprised someone has not built a tc/boat and call it a 'Lance-a-yacht'.
So many folks unload the camper at a site, why not unload it onto a platform fabricated to fit the camper, situated on a pontoon boat trailer that you tow. The camper could fit right into a secure box type platform to secure it .
As you raise the camper, you would pull forward then set the camper down on the platform on the trailer, now back it down a launch ramp and sail away.
I guess it would end looking something like this
