We went to the RV show here in Austin,TX and looked at what TT Princess Craft had out. I saw the 21 and liked it but the aluminum cabinet doors were so small. The space behind the door on some of the cabinets was 3 times larger. My wife was could not believe it. She is so glad we got one of the last 16TBS with the old style snap lock doors. I guess they saved 20$ by making the doors smaller.
