I have been a busy bee around my house with these modifications. Here is a picture of my battery cutoff switch on the inside rail.
Another mod that we did a Corian counter top cutting board on top of stove top for more counter space.
Another mod that we did was the rear clothesline that fits under our rear bunk.
Another mod that we did was the bike rack we placed inside the camper, when we arrive at the camp site we take it out of the camper and use it to store our bikes outside.
We also made a shelf to store our dishes above the sink and the dishes are still on one area when we arrive at the camp site.
