Best of success with your new coach Rick!
When we bought our first camper, we got it at the old Angola sales facility in Lakeland, FL. It was a dream come true. At that time they'd had 18 used coaches to choose from...a range of an 84 Executive to a new plastic H3 (all this before slides).
We were there for over a week picking through every single one of them and had the codes for all the campers so we could look through each one at night when the sales guys were gone. (Best way).
In the end, we picked what we thought would work best for us; a coach which was not at all what we thought we wanted, but the best we could afford at that time.
We stayed there for over a week, took a 3-day trip and went back for The Tweak, which made a lot of difference in our confidence factor and reliability for several years afterwards. Lord only knows we wanted to roll on Day One but glad we didn't.
You'll find that Prevost will do their best to support your purchase and that the component manuals, if properly organized, will give you lots of information. Remember the shell is 80,000+ parts bolted together in addition to the components. How all that comes together is a measure of the condition of the coach and how it runs.
Just one way of looking at it. Have fun and enjoy your new camper. That's what it is all about!
