Not a bad direction to take since you don't plan on driving it much but note with 55k, you'll most likely replace front and rear differentials, compressor for suspension, and front/rear bushings- will cost a few $$$ easily. As for the GYs, consider replacing them soon for your own peace of mind and quiet ride! keep it aligned and keep the air pressure up too. You won't regret it! Good luck!
I thought the differential problem was fixed as was the compressors on the 07 model? I thought the only thing i'd have to worry about was the suspension airbags,
bushings I understand but I can afford to replace those things. anyways... I'm hoping that nothing serious happens for at least a year or two and that I have a great chance of spending way less than the warranty would cost me.
I don't plan to take it offroad much (unless you count potholes on lakeshore drive) and it is kept in a heated garage so hopefully it will last, the history is good so I know its not a lemon so hopefully it will be durable and I can hang on to this great truck for as long as possible. I'm going to replace the tires asap, that with a few other things like a dog guard, cargo liner and i'll be all set for the summer when it comes!
And I paid 24k + 2k of BS/taxes
I got the color combo and model year I wanted though and its in pretty good shape so I can't complain!
