No idea what the "MSRP" for an RV means?? It does seem to be some made up number so that they can then say "35% off MSRP!!"...
Of course the dealer still has to make a few bucks on any deal they make.. Just as the manufacturer has to make a few bucks on any deal they make. That seems to be the 'game' of it all.. You want the best price and the dealer will either let you walk or not.
I compared prices and found the rig I wanted back in 2019 for the price I was willing to pay for it.. I think I can still get that same price I paid for it back then if I were to sell it now.. But, then to replace it, I would be paying a lot more.
Just like my house.. I can sell it now for a lot more then I paid for it back in 1998.. It's actually paid off now too! :) But, to get into anything even close to what I have now I'd be back to a having a mortgage again!
Anyway, buy what you want when you want it, as the prices are not going to get cheaper the longer you wait these days...
Good luck! Mitch
