The <30ft is from the back of the king bed to the coupler, exterior measurement. Not interior living space. That said, I know how TM describes the measurement, and I get it. . But look at any For Sale ad; almost everyone thinks the first number is the open length. The only way for a 3326 to go from 26ft closed to 33ft open (or any other model to do the equivalent) is if the rear bed actually slid out a full 7ft.

And a lot of manufacturers (Keystone, for example) have gone back to using box length in model numbers.
