I've done some upgrades to the truck, e.g., transfer flow 45 gallon fuel tank, banks intercooler and intake system, 4 inch exhaust, Idaho Rob towing tune, extang auxiliary fuel filter, Firestone airbags, head gaskets (ouch) with an ARP stud kit, larger radiator capacity, and a few other minor modifications. I like the truck but my wife is concerned about dependability as it continues to age and we do more traveling. I'm not sure if the features on a newer truck would be worth the large expense. I am inclined to keep it and hopefully it will continue to be a dependable vehicle. I am glad to see others out there with trucks my age and mileage who are still using them to tow their RV's.
