I commend you for doing your due diligence by getting an inspection. IMO, it is wise to get an independent professional inspection before buying any vehicle and includes MH. I hear buyers all the time say, "I found a really clean MH" well, it should be clean, It was just detailed! Many used RV dealers detail them before selling them. I know PPL Motorhomes does. It's what you don't see that. An co$t you big time.
Good luck with your inspection and new FUN Lifestyle of RVing!!!
