I think a few misread the OP. The OP lives in the city, a two hour drive to his property. He wants trailer, so he does not have to drive back/forth.
Now the trailer is just 20 miles from his property. I would air the tires. If they can hold air, even for the day, I'd have it towed, using those old tires. Even at very low speed, it would not take long to get there. The towing people can block it up, leveling it, and done.
Now if it were me, I'd buy a newer, nicer trailer, that I could deal with myself. When done with it, sell it, and the purchaser could easily move it to his location.
