I added a counter top extension to my 2010 Keystone Hideout and thought I'd share how I did it.
I got the shelf through my dealer. It's from a shelf in another higher end Keystone model that is also used as a counter extension. When I bought the travel trailer this was part of the deal I made so I don't know what the cost would be.
Since the paneling is just 1/4" thick a frame work is needed to make it solid enough.
This picture shows two 1x4 boards that I screwed to the frame work.
This picture shows a couple boards I stuck in between the first boards in the area the brackets will be. These happen to be 3/4" plywood just because I had a couple scrap pieces that happened to be the size I needed.
The finished result.
