Got 40,000 on mine now and will trade it off before it hits 100K, which will be in 3 or more years. Be ready to get a new one, be it a 1/2, or 1 ton either way, depending on what we decide to do about camping and the economic situation. Drive it everyday to/from work, so we'll make a decision at trade in time. Right now, the truck and camper are perfect for us. If we camp more or decide to full time at retirement, we will choose accordingly. Probably would not keep any truck more than 7-10 years either way as the new trucks electronics are way to expensive to have fixed, not if but when they go bad.
