I did buy the truck new and problems started at 8000 miles, with the first coolant leak. It was the middle of winter and we were in the mountains on a weekend and had a tough time finding Dexcool. In answer to some other questions, the truck has not been modified.
I appreciate that some owners here have more inclination to know more about their trucks and their campers. I have a very busy life, professionally and recreationally, and I think that outlaying $60K on a truck should provide the owner with reliability and cost efficient dependability.
I had an excellent, experienced service advisor at the dealership where I bought the truck, and during the financial meltdown he was put out to pasture in one of those ill conceived cost cutting measures. When the dust settled from that, I moved my servicing to another dealership that had kept its senior service staff. Unfortunately it is on the other side of the city and it's 90 minutes to get there, drop the vehicle off, and get downtown to work. You can well imagine how old that gets multiple times a year.
We unloaded the camper on the weekend and put the canopy on. When I muster my courage, I will seek out the independent mechanic that's been recommended. I am still thinking about putting up a sign on the road that says "UNLOCKED TRUCK WITH KEYS IN IGNITION HERE", but emptying the change tray before I do. :)
