OP - Lots of input here, and here is a bit more
!
Pick your budget range, do reserve some funds for catch up maintenance and minor modifications to make it our coach.
Then go look, online (PPL does a good job of pictures and floor plans, and look under the sold sections too.) and hit a few larger dealers to go kick some tires.
Make a list of Must Have's and Nice to Have's that matters to the two of you. Narrow down your target coaches to manufacture, models and years that you feel matches what the two of you want.
Then go shopping.
IMO, drop years to remain within budget range, and buy the highest quality coach that you can. I'd rather have a few years older Monaco Signature or Executive, then a Diplomat. (Just and example naming those two.).
Higher end coaches, usually have higher end chassis (Spartan and Freightliner and Roadmaster - come in many different levels of quality and components.)
A short list of manufactures and models that we had narrowed our search down to (Which may not at all match what you two come up with
!):
-Alpine
-Beaver (Patriot Thunder was the sweet spot for us, but also looked at Marquis)
-Monaco (Executive/Signature (And the Holiday Rambler Equivalent.)
-Newmar (Mountain Aire and above. Though we liked the Mountain Aire, as it had less 'bling'.)
-Foretravel (U270, U295, U320)
-Country Coach (Allure, Intrigue, Monaco - Intrigue seemed to be the sweet spot for us in the model line up. As it had the optional CAT C12 available.)
-Travel Supreme
We also liked the hard to find Tripple E, and Rexhall had a very safe DP, with the T-Rex slides. So this makes smaller length coaches much more easier to live in.). We also saw several National DP's that we felt were, like the Rexhall, very good bang for the bucks
!
Ended up with the 40' Allure, because my DW loved the non slide kitchen (More overhead cabinet space without the slide.) - so Happy Wife was more important then me getting the BIG BLOCK engine I preferred. (The mid size ISL does fine in this coach, but the C12 or C13 in an Intrigue or Magna, would have pleased me more. Yes for the power, but more so for the larger block's Braking Horsepower of the Jake Compression.)
The danger of going out shopping before you two have your short list - is you could come home with a coach that you later regret buying.
Happy hunting,
Smitty
