re: Question about buying a 2011 Tahoe

What are you looking to tow and how far? Most campers are pretty light and even something like a Honda Pilot can tow 3500 lbs. On a vehicle that heavy you are going to have a lot of things to fix that are not cheap with that many miles on it. Those full size vehicles are heavy so things tend to wear out faster and are more expensive than smaller vehicles.

Honestly it sounds like your wife wants more vehicle than you can afford. I'd look at how much you have to tow, then set a budget, and finally look at what type of vehicles you can get inside of that budget.
