We have a 2010 GT 330TS with a queensize bed, but it's presently at the dealer's over 2 hours away.
As with most threads I've seen, the basic mattress in most models is a common sore point (soory for the pun) amongst most users. We have a first class queensize pillow top mattress in the guest bedroom which doesn't get as much use as we're planning for the MH.
According to the floorplans for our model, the mattress is supposed to be 60" X 74". Can anyone confirm this measurement for sure?
