Buying a new fifth wheel.
I got mine for '1/3 off', but it was last year's model, and it took a month of haggling. Basically, I told them I wasn't buying new, but I'd buy this one as if it was used. I got the used value from the NADA guide. (
www.nadaguides.com I think) Also, whenever haggling with car (and now RV) dealers, I only deal in 'out the door' price. That keeps those unexpected extra charges from creeping in. Also makes them do all the work figuring out how much I'm really paying.
To get the best price, you MUST be willing to walk out the door. On mine, we were $1200 apart in
price when 'they could not do any better'. I walked out and one month later I called and offered $200 more than my last offer and they took it.
