Another possible idea for safely launching and retrieving boats:
My bus has a 2" receiver at the front, accessed behind the flip-up front license plate; it's substantially bolted to the main frame rails, so it's not going anywhere. I can plug a heavy-duty 12V winch into this receiver, then I can winch things from the front of the bus. This way the bus could be on level terra firma while the boat trailer is safely moved down or up the ramp. I suppose one could also do this with the usual rear receiver hitch, but I prefer to not back up to ramps, even with rear-view cameras and spotters to help me.
Could you put a receiver in the front of your bus?
What I am looking for is having a runa round vehicle and a boat. Where I go duck hunting I have to park in the rv park which is about 2 miles from the ramp. I want to be able to get there, drop the truck and set up camp. Then in the morning and evening go launch the boat. It would be too much trouble to launch at this spot with a bus. I don't believe I want any part of that. The other part is I don't want to leave the boat at the ramp while I am not there. Somebody will walk off with a propeller, battery decoys or the motor for that matter. It is the Texas coast and things that aren't eyeballed by the owner have a tendency to walk away. I believe a double tow is in the works here.
