"MSRP = Manufacturer's Suggested Retail Price ... what part of this definition tells you the dealer sets the MSRP"
Well, the fact that there are very few RV manufacturers (Jayco is one I know of) who post MSRP's on their sites (unlike the auto industry) it gives the dealers the ability to come up with an inflated number, put in their "sale" deduction which brings it back down to the real value of the trailer whilst making you think you're already getting a great deal. "We can't go any lower...it's already our sale price." Not really...:R
Using the link above (thanks BTW :)) pretty much confirms this theory. They add say 30% to the price which becomes their MSRP, subtract that 30% (or less in some cases) and there you have it....their "sale" price now has come back down to the actual MSRP.
