One reason it went so fast was that I used my new aluminum 3 ton floor jack from Costco:

This made it very easy for me to jack the camper up so that Tom set the jackstands in place.
We also used a 12volt impact wrench from harbor freight. The lug nuts were on really tight...it was as though the studs were coated with tar. We thought maybe they were stripped by whoever put them on but they were not stripped. We had the tires balanced and when we installed them we put white lithium grease on the studs and it was much easier to the the nuts back on. We finished up with our torque wrench at the required 90-95 lbs.
We were amazed at how out of balance the tires must have been...because of the size of the wheel weights that they had to install. We always thought the TM pulled very smoothly and look forward to seeing how it pulls now.
