Mark, I am excited to watch your search and purchase please keep us all updated as you progress through the process.
As far as coaches, I have a few friends from my aunt/uncles' motorhome club that have some high end coaches. One bought a used Prevost/Marathon and they have really enjoyed it. I believe it is a 2008 model year and they bought it when it was a year old. Great looking coach and very well built from what I can tell by the little I have been in it.
Another friend of ours is on their third Newell. Their first was a 1988 40' with the two-stroke Detroit. Their son now owns it and it has approx. 215k on the odometer. Could use a paint job but other than that everything works tops.
When they sold the 1988 to their son, they purchased a used 2003 45' from the factory that was reconditioned, it had the Detroit Series 60 engine and ran fantastic even though the coach weighed over 50k pounds. They towed a 22' enclosed trailer to Alaska three times with a Buick Enclave and full size washer/dryer in the trailer. They went off of the road in a freak not paying attention to the turn incident several years ago and tweaked the coach something awful to where the galley slide wedged into the chassis. At first I thought maybe a weak chassis design until they told me about where this "hole" was that they hit. The next time the wife and I drove past it I was amazed as the hole was about 2' deep and probably 6' across. I was then surprised it didn't total the coach.
They drove the coach back to Miami, OK to have it repaired. When I heard they were on their way back home within a few days I thought that was a fast repair, must not have been that bad. I then found out that they traded their 2003 45' in on a 2006 47' model and were on their way home with it.
It is an absolutely amazing coach. We were camping with him one time and one the guys who had a Prevost asked him why if he was spending all of that money didn't he buy a Prevost chassised coach. He said "why would I go backwards". I know they joke with each other about the Newell vs. Prevost but this guy swears by the Newells and will have nothing but. Don't get me wrong, I am not downplaying Prevosts, just passing along a story/comment.
Good luck in your search.
Mike.
On edit, have you given any thought to Foretravel? I think they are extremely well built as well.
