kirkifer, I would look at the prevosts as well look at the best non-Prevosts out there - Foretravel, Beaver, especiallly the Beaver Emerald, Monaco Signature, Country Coach Affinity. At 100K you can get a good coach which will last for years.
Financing may be an issue, as you are looking at coach ages where a long-term loan just based on the coach may be a problem. You may need to base your financing on your house, depending on your down payment and the age of the coach. Normally, a 20 or 25 year top end is all the banks will do on the coach, but you need to ask questions.
