i wonder if you could get some drawer slides at Home Depot and hot glue and rivet them to the sides of trays ?
if not i would just make some wood drawers with some full extending slides
i may have to make some for my camper because the only drawers under the sink are just about on the floor
good luck i hope this helps
I don't know if this will help you out or not, but I ran across this site today and thought of your post. http://www.slidingshelf.com/ Maybe they'll have something that will match your wood grain finish and also fit the area that you're working on? Looks like they even have a custom orders section. Now that i'm curious, I may see what they have for my little Roo...never can have too much storage in one of these things, that's for sure.
Where we've been:
2000 Rockwood Roo M-18 Hybrid
2006 Dodge Ram 2500 Auto 5.9 Diesel
Gone but not forgotten -1986 Rockwood 1003 PUP
One idea, you could add a piece of wood or metal to each draw on the bottom and place it where ever you need it to stop. The wood or metal would have to extend past the bottom of the draw so that it would make contact with two vertical picecs of cabinet draw opening, and could also add a second piece inside of each draw for add support.....Do you know what i am getting at?
