Kitchen overhead cabinets have tapered and obstructed storage

I know the original question was about the drawers, but just a quick comment on the measurements above for the overhead kitchen cabinets. Since those are factory specs, I'll take that at face value. However, don't count on having that full height/width/depth uniformly because those cabinets are not perfectly rectangular. The top back corner of both is rounded to follow the exterior contour of the Pebble, so it starts tapering inward at about 7" height, making it shallower at the top.

The left one (over the sink) is that full stated width but it also has a couple of 6-inch-wide "bump-outs" that intrude 2–3 inches into the cabinet space, making them shallower at those points. The right one (over the counter) doesn't have the bump-outs, but about 12" or so on the left is taken up by the housing for the ductwork and electricals for the hood vent over the stove, so you really only have 20-something inches of usable storage in that cabinet.

Bottom line: I'd suggest not trying to buy anything to fit those until you actually have the trailer and can see for yourself.
