My hangar is uphill in. I bought a winch at Harbor Freight and mounted it to a vertical steel post. I can pull my plane in. You can also bolt it to the floor. I can push it out by hand.
Most of the guys that have a tug end up with a 4 wheeler. Get one of the used Hondas that have an in front kit for a trailer hitch and get a tow bar. Pulling it in is best if you have the hangar depth. If not, with the right tow bar, you can push it. Best to use the trailer hitch on front. Those 4 wheelers are a blast driving around the airport and fit under a high wing.
YMMV.
