any one have one or seen one of these ?

Yea, looks like a TT mounted on a basement/ 5th wheel mount system. Especially when you look at the interior entry well/steps. No need for that setup if designed as a 5th wheel from the start. And why carry the floor flat all the way to the 5th wheel mount then step up to make the hitch connection? Rather cumbersome. I don't need all the basement in mine now (and I live full time in it) so why all that storage? The carrying capacity doesn't look very high as the 5th wheel isn't beefy enough. Not for me!
