We have the standard table in the 21 and love the large flat surface since we really didnt have a table in our last trailer. We have a filler board that we can put at either end of the table to prop our feet up. It depends if we want to look out the window or watch tv. Climbing over it to get out is tough. We are having fun tweeking the arrangement. May end up with a collection of various tables to choose from.
U dinette with the marine telescopic hydraulic table lifter (mounted to floor) and two way slides on the table top. Lower it for lounging and reading with a couple of bolster pillows, and the table top sliding mechanism (which can be locked) makes it easy to get in and out when in dinette mode....we're only two, but the Labrador thinks it's her bed when we crawl up into the bedroom.
