Definitely low-tech but probably the single most useful thing I've
ever added is a little 3-legged stool that I can sit on while
cooking, washing dishes, etc. I can reach everything I need but can
immediately move it out of the way if need be. I often stay sitting
in it while having dinner at the swing-out table rather than
squeezing in with my wife on the bench seat.

Got it at REI for cheap: It's just metal legs and a canvas seat.
Folded up, it tucks up amid the canvas in front of the latch that
holds down the pop-top.

Sometimes it's the little things that matter most,
