Again thanks for the comments, I do appreciate them.
John Wayne, you are correct, it is a class A, I had previously looked at a Class C, I mis-typed. I did read about the plug issue, that's what originally had me not liking the V10, but after further research, I found many more positive than negative. I agree about the old hose clamps, never liked the spring type. I'll check the air filter snorkel and look for the P1 stamp.
mike brez - it did have a leak at the bath skylight, but has been repaired and re-caulked.
Since I am somewhat of a DIY'er, and still fairly young (in my mind), I'd do most of the maintenance. Always have and I've had 3 trucks go well over 300k miles in my time. Tires are 3 years old, and have good tread on them. Was going to have it diagnostic scoped to check compression and see if any other issues are present prior to making a final deal.
