Not a lot so far! And yes, I've had the same problem with the cheap boxes.

It seems to me that drawers are great for some, or for constant traveling, but they prevent being able to move stuff out of the truck and into a camp. I was thinking of knocking up a draw type framework, but using some sort of better quality box instead of drawers. The other downside of drawers is they don't come out very easily when home and the vehicle is being used as a daily driver.

Searching the internet for plastic boxes brings up a million hits on crap, so I was hoping someone might have come across something and be able to point me in the right direction.
