Am I missing something? ......................
You aer looking for a liveaboard that is trailerable?
Those seem to be, if not mutually exclusive, then at least mutually unneeded?
Usually the point of living aboard is that the boat is in the water all the time; and you don't need any land.
I got an Old Fat Boat
She's Slow But Handsome
Hard In The Chine, but Soft In The Transom
I Love Her Well, And She Must Love Me
But I think It's Only For My Money
