I recall something like this being asked some time ago... The basic explanation that was proposed was that the truck was lighter sprung on the passenger side so that when the fuel tank is full and the driver were sitting in the truck, it would be even. I think that's a load of crap! Still, no one offered anything better, so that was accepted by the thread starter....
My thoughts would go to worn shocks/coilovers. With that kind of mileage, it would not be uncommon for the stock shocks to have given up. Just my .03......(adjusted for inflation)
