Not sure what to tell you. I live close to Mechanicsburg, but as CUCVFAN said, I'm not crazy about the idea of telling someone that I looked it over and it's ok to go. I don't want that liability on my head. Getting these things running is the easy part. It's everything else that's hard. Several trucks i picked up ran like tops, but had no brakes.
I bought one truck more than 50 miles from me and I'll never do it again. It was a safe recovery, got home safe and sound and i'm experienced with these trucks, but I had problems coming home that I never thought I would have. Truck spent the night along the road in one state, and me in another. Again, all was ok, but I had plans, B, C, and D and am somewhat resourceful. Mechanicsburg to MA is a whole new ballgame.
Just curious, why did you bid on a truck so far away? I didn't see this truck, so have no idea, nor do I have any idea if there a bases with trucks closer or not, but just curious.
If you do the recovery, try to allow extra time the day of, and NOT on base. You'll have to remove relatively quickly. But I'd get it off base safely and then find a lot or something close by to work on things. There are several truck stops not far away. Just a thought.
If I'm up there sometime soon, I'll take a look, but I'm not a mechanic and hold no responsibility for my opinion. After that, if you need assistance on getting out of there once you come to recover, I may be able to help.
