I'm thinking about mod'ing the storage access door area that our pup has for getting into the trunk area from inside the pup. We have access from outside and the outside side access is available too. I'd like to build a 'box' enclosure with a shelf so that when I open the access doors on the inside I have two storage shelves. I'd also make the 'box' where the light is still accessible. Not sure about what to store there, but extra blankets, our clothes, or even make a small pantry. I do know that the trunk area is prone to possible leaks, so I'd need to remedy that with the type of material used so that it doesn't fall apart or warp if it were to get wet. Any pro's or con's that I need to think about? Here's a rough idea of what I'm wanting to do.
