I increased the number of breakers to four, added 7 dual AC outlets (3 with built in USB ports) and four DC outlets to our 1991 Scamp
I AC outlet and one DC outlet is under the dinette table in a dinette bench face. I used a saber saw to cut out a hole for the AC outlet and drilled a hole for the DC outlet.
I put an ac outlet in the 45 degree face of each dinette. These outlets each have two USB ports.
I put an AC outlet in the shelf area under the kitchen sink. Our Air conditioner located in the bottom of the close and the AC modification to the hotwater heater plug into this outlet.
I have two AC outlets under the front couch. One is for our new AC-DC Converter. The other is in the face of the couch base. It allows me to plug in the computer while writing.
Above the end of our couch is a cabinet. Below the cabinet is another 12 vDC outlet.
There is another DC outlet in the cabinet over the stove. I mostly use this one for my DC compressor for adjusting the door side tire.
came with AC outlets in the ends of both kitchen cabinets. I replaced one of these outlets wit an outlet containing two USB port chargers
Lastly, under the trailer there are two AC outlets on the door side mounted on the frame at the rear in a 'water' proof metal box.
My breaker box is under the sink. For the outside outlets I ran wire from the breaker box under the dinette seat and drilled a hole through the floor running the wire to the waterproof metal box, the kind you see on the outside of houses with opening metal covers.
I sometimes use the DC outlets to plug in a 100W cigarette lighter inverter (12 volt to 110 AC inverter) to run the TV. The TV takes very little power, the order of 20-30 watts.
I similarly ran other wires to the other boxes. I attempted to divide the various circuits up so no breaker sees a lot of current at one time. We have not had a breaker pop in 6 years.
There is also a 12 VDC outlet in the panel behind the refrigerator
, right above the rear tire. I use this one for plugging my DC compressor in to put air in that tire.
We do have a lot of outlets. The USB outlets are handy for charging our phones, Amazon Pad and E readers.
The boxes, wire and outlets all come from Lowes, regular home stuff. I typically use the blue plastic boxes with the rear ears to hold them in place.
I have also replaced one of Scamp's old outlet boxes.
I do not hesitate to cut the interior fiberglass. Besides cutting hole for outlets I've cut the the fiberglass to add 6 drawers, an Air Conditioner and a hamper.
I have not reinforced any of the cuts for drawers and we have some a foot high under one dinette. The fiberglass is really strong but if you choose it's easy to reinforce with 1x3 material
