One note on the lights - do take voltage readings at every one of them, you may be surprised at what you find. Case in point my sunline has the lights all daisy-chained, basically from the electrical panel in the front left corner the wires go back to the driver-side brake light, then over to the passenger side brake light, up to the top clearance lights on the rear wall, then all the way forward to the front right corner clearance light, and from there all the way over to the left clearance light - made for a huge voltage drop between the panel and the top left clearance light, had to run another set of power and ground wires from the panel up to that front clearance light so now current has to paths to follow around between the different lights, it worked great. I also installed a relay for all the running lights, and doubled-up the power supply to the camper with a 6-gauge cable coming directly from the driver-side truck batter and going straight into the camper's converter unit (as opposed to the factory setup using a long harness to hook up to the 7-way on the rear bumper). All in all she glows like a christmas tree now, nice and bright, and the water pump has more oomph to it too.
