Best older motor homes ?

Hey there, I'm new here and am looking to buy my first motor home. I am trying to find websites and other resources to find which makes and models have the best reputation for reliability, fuel economy, ease of repairs and availability of and cost of replacement parts. I will also be traveling and living with two cats and towing a Sportster motorcycle. Any and all tips and information will be greatly appreciated ! Oh, and I thought I'd add that I have already read Bill Myers book about how to buy a used RV. It was great ! But I still have many questions and am seeking advice from you experts who have been there and done that ! This will be my home on wheels that I am looking for and cannot afford any major screw-up's in the decision making process. Thanks again everybody !
