The three shelf, pull out cabinet, next to the stove in many Montanas is a nice idea but another example of poor implementation. The shelf rails are too low to keep objects in place when rocking and rolling down the road. The end result is the contents bounce off the shelf and into never-never land of the surrounding cabinet. Extensive use of pressure bars helps keep things in place but makes accessing a specific can or bottle even more difficult than it was before.
We found these baskets at our local Organize It store. They are 16" wide and 6" deep with sides up to 4" tall. Manufactured by Schulte, I found some at Amazon
"Clicky" albeit at about twice the price of what we paid (~ $8.00 each)
Here is a basket with our commonly used spices. They stay put when traveling and are easy to access. Just pull out the basket and grab the one you need. No need to be down on your knees searching for that elusive bottle.
The baskets are a prefect fit width-wise. The shelf is a bit longer than the basket which allows for easy insertion and removal plus space to store larger containers.
