Time for Plan-B. Winch it in. I got the winch at WalMart for about 70-bucks. It has a removable bracket that can be hooked over a hitch ball. The bracket is also predrilled for mounting on a solid surface.
I installed the mounting plate to the floor of the TT. I don't carry the winch with me. It stays in the garage and gets hooked on the the trailer when I want to move the TT inside. I power the winch from the 12-volt batteries on the TT.
The winch comes with 29-feet of cable which is not enough to get all the way into the garage. I added 10 feet of light chain, attached to a simple loop anchor plate that is Tap-Conned to the floor.
Getting the TT out of the garage is easier too. I roll the TT out the door to the edge of the driveway. then I "lower" it down the driveway and remove the wheel disks and install the tires.
