When we bought are G284FLT 5th wheel we got 30 percent off MSRP plus a number of perks like a new MorRyde king 20k box, upgraded TV antenna an winterized free of charge since we bought in January an the dealer had De-winterized the unit to shows us everything worked an had no leaks ...
Are unit with all the bells an whistles was listed at 95K MSRP we bought it a 62K out the door :)
