I'm not trying to speculate, but some (not all) sales men are notorious liars. The best way to find out is to email or call Dynamax, I find them to be very responsive. You can find a link with phone # and email on their website.
B.t.w.: We bought ours at Vision RV and I must say we made the right choice, if spending that kind of money on an RV can be considered a good decision.
