You have a nice looking truck, you are further along than I am on the 5 ton camper project. I have A 1990 M923A2 that I have been working on . So far I have done some injector pump adjustments and exhaust improvements. I have added a pyrometer to keep tabs on the exhaust temperatures and i'm in the middle of doing some air filter housing modifications. In the cab I have an air ride seat for the driver and a 24 volt stereo . Until I can build a camper for it I will use my Pine Mountain 800 in the bed. Only problem is I need to build a lift system to get it in and out of the bed.
