Advice on buying older diesel

Thanks everyone. She has been very forthcoming about the motorhome, and did tell me that it suffered from the classic mid 90s Monaco problem of a leak behind where the awning mounts to the frame. She caught it early and had it resealed, but it caused some delamination along the top ridge. This was 2 years ago and she said it is solid if you hit it with your hand and the delamination hasn't increased at all. I have read stories about immediately running away if there is any delam, but I have also read that when you are talking about coaches that are 20 years old, you are going to see it pretty frequently. She claims it is just fine and that she doesn't think the RV inspector will be that concerned about it at all. You can kind of see it under the awning in this pic:



So do you think it is worth paying the $290 to get it inspected or should I just walk away?
