Forrest brings up a real good point often overlooked. There's a real
big reason Airstream made the cabinetry from 1/4" and 1'2" veneered
plywood and the doors are hollow core. You'd be surprised at the number
of times I've come across interior remodels where someone used 3/4"
plywood and custom solid wood cabinet doors on an older trailer, and the
owner wondered how their trailer got to be so heavy and harder to tow.
If you throw a big enough tow vehicle at it, that can be overcome, but
then there's the issue of the extra weight on the frame and shell that
it wasn't designed for, resulting in frame/floor/skin separation and
loosening.
Solution? Custom cabinets are fine, but think like an aircraft designer:
lightweight but sturdy using quality materials and construction methods.
