Look at the room in this TL252DS!

On edit, based on what has been said many pages back on this thread about B+ units w/ dinette or sofa slides, you cannot make the big king bed because even when closing in the slides, the folded-out jacknife sofa does not meet the dinette, so you are left with two separate small beds.
How noticeable do any of you think the extra wt. of two slides and the extra length would be compared w/ a TL 213 of same 6.0 Chevy?
I like Holman's no nonsense pricing, and would seriously consider driving there if I ever wanted to trade for another RV.
