I bought my 98. 5 new: it how has close to 170,000 miles on it. I replaced the lift pump at 117,000, brake pads at 86,000 and have changed batteries twice. I have had no problems with the VP or anything else. It is a great truck. Averages about 19 miles per gallon, my ususal driving: has gotten a high of 22. 4. I use Amsoil in engine, transmission and differential.
