My 2001 is 1 1/2 yrs old and I have gone through 3 sets of shock absorbers, oem, Ranchos, Monroe Gas Magnums. I have just ordered a set of Bilstiens, and will install them this week. I have a slide in camper on the truck permanently (my home). I know from this forum that several of you have similar set ups. I would appreciate hearing from others having similar problems and any suggestions/solutions. Thanks.
