I have put about 1.5 k miles on the camper with no problems. Here are a couple of things I didn't post on.
For the front facing window I made a very simple rock guard. I bought a cord guard like this one:

And cut it, painted it black and silicone caulked it into place at the top and bottom of the window frame. I bought a piece of corrugated plastic and cut it to size and just slide it into the Channel created with the cord guard. It cost about 18 dollars and took about an hour to do. Also as KC suggested I secured the board that holds the battery box to the tongue with square shoulders u bolts on either side.
