Enclosed Race Trailer Setups, Lets See Them....

Just picked up a used 24' after selling my 24'. This one has heavier duty axles, and a drivers side escape door, and E-rated tires, but basically similar to my old trailer with white walls and ceiling and grey floor and a couple of 12v lights.

I am thinking of putting a tongue box on it and hiding the 12v battery for the wireless winch in there along with a trickle charger and a generator cord. My question what is the best way to setup the 110v outlets and the air, I use a 20lb CO2 tank for air?

Put 110 outlet on the front and rear left side inside and out.

I have 110 inside and out... with 4 foot 110 florescent
lights inside(2 double bulbers per side) with a small
compressor in my cabinets that wired in with a couple
of air outlets(non out side) but I want to add one
at the rear door... I have a 4500 Onan gen mounted
in the bed of the truck

First trailer.
