I have finished the installation and also a near complete refurbishment of the scamp
Here is what I came up with for the solar
I bought a $265 kit from Amazon and added #8 cables for a total of about $300.
The kit had to 100w ridgid panels and a 30 amp controller.
I mounted the panels by simply bending the mounting brackets to match the roof and I used 5200 to glue them on.
The controller is mounted under the stairs to the bed.
I have two group 31 agm batteries mounted on the front landing gear bracket and a 1000w aims full sinewave inverter.
This powers my 4.5 cubic foot two door refrigerator
with no issues.
, panels and batteries cost about $1100 with me doing the installation.
