If you do go see the Lance, and you end up wanting to purchase it, I would make sure it is ready to take home with you. When I purchased mine, the dealer wanted a day to make sure it was all ready to go, I suppose if he had found something, he may have to order a part. I went back the following week to get the walk through with the lead Tech service guy. I guess what I am saying is, you probably dont want to make the trip twice. Ensure the overhead clears the cab and oh yeah, Lance has its own 5 way plug. I brought mine home using magnetic trailer tow lights..... taped to the aluminum bumper.
Good luck.
