I do own a diesel pusher but I'm no expert. I think the only thing that would concern me about buying a used one (and it concerns me about the one I have as it gets older) is things that break on a diesel pusher tend to be way more expensive than things on smaller gas motorhomes. I've heard stories of blown engines costing $25k to replace and a transmission being $12k or more. I have no idea if that's true or not as I haven't priced them out. All I do know is if my engine does blow and if it does cost $25k to replace, then my motorhome is going to become a really expensive guest cottage that sits next to the house for the rest of its life.
