Gone to diesel? Some questions for those that have.

My diesel swap was the best thing I ever did as towing is concerned. Power is not a problem, distance between fill ups are incredible now while towing, and I only change my oil & filter once a year now. Can't complain about anything on the truck at 100k miles, except I feel the paint could have a little more life to it, and I wax it all the time, but at the right angle I see micro spider cracks in it.
