Rob, have you tried the little stick on levels? I have one on the tongue and one center rear. Open the trailer and level it as close to 100% as you can and Stick them on. They may not wind up 100% level but note the numbers that are on the backround and repeat at the next campsite. Mine work pretty good to get the initial side to side and front to back b4 opening. Then I put a torpedo level on top of the fridge and get it to where I want it from that. I doubt if I spend 10 minutes at it. Depends on how anal I am that day.
Also, a 18 Volt drill will pick it up right off the ground.
