note that the "MSRP" is usually a typed up sheet of paper, often generated by the selling dealer. Who knows where the numbers came from. Used to be that way on cars until the "Maroney" sticker was required (1958?). It required the mfg to print a price sheet with a VIN number along with all options and a list of standard equipment, warranty statement and that this sticker be placed on the vehicle only to be removed by the purchaser. Purpose was to keep dealers from publishing phoney MSRP and price lists. AFAIK no such document is required for trailers. (Or at least wasn't required a few years ago). However it does look like some mfg are making real MSRP stickers rather than dealer printed ones. Maybe they are finally realizing it makes sense to have known fixed real MSRP stickers.
