The shows have potential but you really must shop around. When I was looking for the coach I have now I set my budget and started searching everywhere east of the Mississippi. If I could find the coach I wanted in Memphis (live in south easter Virginia) with a $10,000 savings over another seller closer to home I would be on the way to Memphis.
I would also wait until you get a bit closer to retirement. Probably the year prior. Will give you a year to work thru warranty issues and time to make shorter trips to get to know the coach. Hit the road in year two with a coach you can trust and never look back.
