How to move two trailers at once? I'm moving?

I have a ford f350 and am renting a big u-haul to move my stuff. I also have a boat(no I'm not selling it) it's my only vehicle, what's my best plan of action here? Not paying any company to help either.

Then you are going to have to make two round trips, once hauling the trailer and again hauling the boat. You can't tow two trailers at one time.

Simple: You CAN'T move two trailers at once unless you have two trucks and two drivers.

Multiple trips, or "hire" a friend to drive the F350.
