Has anyone ever seen a pop-up camper towed in tandem with an inboard? I am envisioning the boat in the middle - removable hitch across the trailer frame rails, behind the prop guard.
The only restriction I can find for Texas is a 65' max length, nothing about a 5th wheel in front.

Combined weight would probably be around 6000 lbs for most combos.
I think it's doable. Maybe slightly "Uncle Buck", but doable. Thoughts?
