Go visit a few dealers, and RV shows, and kick many tires. Go in and sit down, both with he slide opened/closed, and spend sometime visualizing how the two of you will move around in a coach, and sit, and TV angle.
Read up here, IRV2, and other boards, on threads like this (Many, many threads averrable:)!). Learn Pro's and Con's on Side vs Rear radiator; two slides vs more then two slides; tag vs non tag; Jake Compression Brake vs Pac/Exhaust vs Retarder Transmission; propane water heater and heating vs Aqua/Hydro Hot, etc., etc.
Come up with a list of Must Have's and Nice to Have's. Pick a budget range, and then use RVT and PPL, and others, to get some ideas on prices. Narrow your manufacturer and specific models down to a small list. Then start your shopping.
I'm a firm believe in 'Dropping years to remain within budget range, and buy the best quality coach that you can find, that meets your needs.'. Quality lasts, and becomes a solid foundation to modify and upgrade to your personal likes. (Maybe keep a hunk of budget to cover upgrades.).
I also recommend buying the biggest engine you can find in the models you like. They work easier, and usually give you the same or better MPG. They also usually give you a safety edge on a bit more power, and higher braking house power vis the compression braking.
In no particular order:
-Alpine
-Travel Supreme
-Newmar (Mountain Aire and up)
-Monaco (Dynasty and up, and equivalent HR line)
-Beaver Patriot Thunder and up
-Foretravel
-Country Coach (Allure on up)
-Entegra
-Bluebird/Wanderlodge
** On Edit: Meant to include American Coach too. And again, for sure not a complete list. At a bit lower price point but well liked by their owners, add in Rexhall's Roseair and Tripple E too.
This is a partial list of higher quality and good bang for the buck in gently 3-10 years old coaches.
Happy hunting,
