We have two that barely fit in the drivers rear storage (part of the pass through). Let's see if I can find them on the camping world website.....
Well they must be discontinued, or Campingworld doesn't sell them anymore. We purchased two of them years ago when they were on sale for $55 each.
Like I said: they barely fit. Its always a puzzle getting them into the compartment door as I have to remember what the proper orientation is where they will fit, and once one of them is in there is little room to squeeze the other on top of it.
You can see them leaning up against the camper at left in this picture:
And you can see one sitting out next to the picnic table here:
Unfortunately, though, I doubt either pic will help you out.
The one Dave linked to is very similar to our two.
