recently bought a new Excel. Why not send him a PM (Private Message) and see if he has any suggestions.
The highest discount off MSRP that I have seen posted re: Class B's is 21% off of a high end Sprinter model. That's really a lot.
I think 15% is more normal and 18% being about the max. Not every dealer will be able to give 15% off.
This site: http://www.willrepinc.com/
is loaded with info about Pleasure-Way RV's. They even have a MSRP calculator. You can build and price your unit. It's for 2008's but I think the current 2008 might still be on the 2007 Chassis.
Use this link: http://www.willrepinc.com/pleasure_way.html
and scroll down to the bottom of that page and you'll see the 2008 Pleasure-Way MSRP link.
