As stated above, as long as you are happy with the deal, and it does look like a good price, you are good to go. Rest assured you are not fleecing the dealer, their main goal is to make a deal that makes everybody happy, and you can be sure they covered their end quite nicely.
MSRP as the acronym states is a suggested retail price and is manipulated by both dealer and/or manufacturer so they can be sold for what appears to be unbelievable prices. It is why a 25 percent or more off MSRP is expected for most deals. Enjoy your very nice Coachman bunkhouse.
