I have a 2001 Toyota Tundra Limited Edition with a TRD supercharger (supercharger install at 35,000 miles)and many other performance parts. My truck has an aftermarket exhaust (true dual) with the y pipe gone. Also I just turned 200,000 miles. I towed with this truck all the time (Like 25,000 miles a year). I tow a 4,500 pound trailer and I get 9.5 to 10.2 mpg while towing. I get 13 to 18 mpg when not towing and if I stay off the supercharger. The body has NO RUST on it and I kept waxing and doing the upkeep on it. Note: Timing belt was done at 140,000, shocks at 185,000.
Now that you have a better idea what I use the truck for and the condition, MY QUESTION IS... My truck has been recalled for the frame. My frame has been order and I will have the new frame in the next month or so at DUNNING TOYOTA IN ANN ARBOR, MI. QUESTION IS.. What things should I have done since my frame is off? Doing engine or transmission upgrades or rebuilding doesn't make sense because this is drop and not taken apart. They said they would put all new parts in where they take off and do new brake lines and other things. I was thinking that I plan on having this supercharged truck to at least 350,000 miles. Are there any parts or service I should have them do like: timing belt, alternator, shocks, any other things? Should I take pictures of the underside of the truck so i get all my aftermarket parts back like the headers, exhaust, towing hitch, etc?
Thanks in advance.
