Thanks, depending on if and when I get it, I might do something over the 4th since I have a 4 day weekend then as well. I would do my Iowa trip to SIG, but already have a room booked for 2 nights non refundable.
Some great information here, I really appreciate it. I am tossing around the idea of maybe just finding a motor home if I can afford it instead. I doubt it could get much worse gas mileage. :) I did find one that would work well for us, but I don't know if I really want to go that route, much more maintenance involved, and I really don't need another vehicle on my insurance, the TT is only another $98 for 6 months on my insurance. I am pretty confident my truck will not have any problems towing, but my wife doesn't do towing, however she could drive a MH.
Its the 3500 mile RT that really holds me back on the MH, a trailer is much easier to prep, make sure the tires are good and sound, the brakes have enough meat and are adjusted correctly and the bearings well lubed, and you are good to go. The MH, you have the engine, which after so many years you wonder how well it was kept, how long will it last, same with the trans, steering and brakes. Lots to think about, but so far I have a lot covered now. Thanks again to all who answered.
