I really like Dan's more elegant solution (//heartlandowners.org/showthread.php/44103-Ladder-Support?highlight=ladder+support)
Unfortunately I didn't have the time to put it together. What I'd really like to see is a ratcheting spreader that I could use for both the ladder support and inside cabinets to keep things from shifting around during travels. Something similar to a truck cargo bar. Anything that can serve multiple uses is a big bonus when your full timing.
