I am trying to find a new truck, I am looking at m925's. I recently found one close, looks good in pictures. Low milage and recent rebuild interest me, the only problem- question that arose is the actual towing capacity on the road. The seller told me he tows his 20,000lb machine with it. No idea of the trailer weight, but I would guess the trailer is probably all of 5000lbs, should I be worried and not even consider this truck? I think both ways, at least I know it moves some decent weight and is fully functional. The other side to that is has anything been stressed/ damaged by such large tows. In the end what can a truck like this reasonably toe on the road? Any input is much appreciated.
