One of the reasons I agreed to purchasing our RV was the ability to fish further away from home and palaces we wouldn't ordinarily be able to go.
Wife didn't want a pick up for toed so the idea, of a small boat on a rack, out the window. Towing a boat and trailer behind our motor home would make it 80 some feet. Some around here were or do tow a motorcycle trailer or boat and trailer behind fifth wheels, through Alabama where it was or is legal and some other states but I'm not up for towing a whipping snake.
So it is boat rental, the few places that have them. The rates can rung from 200.00 a day and up. That takes the fun out of it.
I guess what I will pursue and should have five yeas a go is a Hummer with a rack for a towed.
A trailer for towed and a second electrically operated elevated rack for a boat and trailer, which I've seen would be good but, in our case, I'm waiting on the lottery.
