You don't need to jack up the trailer. What's all the fuss about.

Just use your front mount jack. Jack the front of the trailer so the front are off the ground. They have collapse so you should have plenty of room. Get them off however you want. Then lower the front main jack so the front is lower and the back ones come off the ground. Then take them off. then jack the front back up. hook it up and drag it out. The tires are probably no good so I would guess not putting air in them won't hurt since you will need new ones.

Don't make this harder than it is. It should be a piece of cake.
