Do you know how to replace DP alternator & belt?

Not to throw salt on your wounds but that is why I love my side radiator. You will be able to fish the belt around the fan in between the shroud, I would have someone up top in the motorhome and someone down below to help if possible. As for unbolting the alternator, make sure that you mark the wires and disconnect both the house batteries as well as the coach batteries. Good luck to you.
