This is what I have always posted when asked about buying a used MH
"Once you find a MH you are interested in, get professional inspections done. If you don't do this BEFORE
you purchase, you run the risk of spending significantly more AFTER
the purchase. If something is found, the inspector should be able to give you an estimate to repair. You can then decide if you want to proceed and can use it to negotiate a better price. You will be going into it with your eyes open. IF nothing is found, GREAT!!
I would suggest that you get an independent certified RV mechanic to inspect all the RV systems, including the roof. In addition I would have the engine, transmission, frame, etc. inspected by a diesel service shop. Having a coolant and oil analysis by a lab (like JG Lubricants ) would reveal any hidden problems.
Make sure everything is in writing!! Any purchase should be contingent upon successfully passing these inspections/tests.
I would do this to any used MH I was looking to buy.
