Since you're asking, I'll assume you've already considered what will fit in storage, getting it through the door and carrying inside, etc...
1) On a trailer or toad
2) On the roof
3) On the back
A quick google search for "Motorhome hitch mount canoe rack" brought me to http://rvkayakrack.com
. They might have something you can use to try carrying it on the back.
If not, as long as it's properly secured you should still be able to use the roof, even with the solar panels up there. Just have to make sure it can't hit the panels. Oh, and watch your height.
