Good idea to take it to the dealer or any shop and have the bust the nuts (haha) loose on the seats. I don't think it is something you'd have to get retightened with an air wrench though. It is probably just because they are put in with an air wrench at the factory. I've taken the seats out of a lot of the vehicles I've own and none have ever been that tight. Put a little blue locktite on the bolts and tighten them normally.
I'm planning on going with the Monstaliner kit as well. I'll wait until Fall for a nice weekend with a high of 75 or 80 degrees.
