I see u have a 409 have you have some reliable/reasonable parts sources for me? I just inherited this motor home it is in decent shape with 111000 mi. I have been searching for various parts and it seems there is no u.s. support for the mercedes truck?or is there? I am afraid of getting stranded somewhere it seems difficult to find lets say a radiator hose.What I am trying to say is that I am having a case of parts anxiety!
