Some manufacturer ship a document with the unit that lists MSRP including a detailed list of all options and packages along with their pricing, most don't. As an example Rockwood/Flagstaff has such a document but its typically the first thing the dealer removes when it's delivered. Also that document and the pricing is the same as I had 3 from 3 different dealers when shopping for our current Rockwood. Ultimatly I paid less than $20K for a trailer with MSRP of $32K. I met a gent at the campground two years ago with the same model from the same dealer who was proud of the fact he only paid $28K lol.
