Ongoing saga of the motorhome

If I read your post correctly, you are relying on the warranty companies inspection to serve as your pre-buy inspection. From what I have seen, their inspection is no where near as thorough as an independent inspector that you are paying to represent you. When I bought my 2008 coach, my inspector spent over 4 hours going over every system, followed by a written report which included mandatory items the dealer needed to fix/replace, and suggested items. I used this report to my advantage with the dealer, who had a deposit but not full payment. I made it very clear no more cash until the rig is as expected. This was an exhaustive process on my part as I ended up doing 3 PDIs, one after each time the dealers techs were back in the coach addressing issues. In the end, they came through, I think only because I had the money and a written report from a local industry expert. It's a big investment, there's only one person, well maybe two if you count an inspector on your payroll, who is going to take care of you. And I promise, the dealer is not the one.
