Chinook RV

I agree with you, BobW9,
and intend to do something similar to your design. My comments are not practical/legal for RV's or home. However I used 15 amp receptacles in DC circuits in my marine electrician days working on Navy ships; the following may be interesting:

320-1.4.2 120-VOLT GROUNDED RECEPTACLES. Since the danger of electrical shock is always present at 120V shipboard circuits, normal practice is to use grounded plugs a Chapter 300, are provided as follows: Double, 120V, 15-ampere, single-phase ac or two-wire dc, bladed-type receptacles for below deck applications. These receptacles are similar in appearance to those used on shore, however, both blades are hot with the third pin as a ground to the ship’s hull. They admit either three-prong grounded plugs or two-prong plugs.Only two-prong plugs attached to double insulated, portable, plastic, electrical equipment (such as shavers,erasers, drills, grinders, and sanders) are permitted in these receptacles on board ship. Double insulated housings do not require grounding for personnel safety. (The 2 wire AC conductors each measured 60VAC to ground and 120 VAC between them.)

Quite a different thing from these solar panel connectors.

Thank you all so much for the input.
When we first got our Chinook I noticed the phone plug by the table and looked for the 'the other end' all over and never found it, had also wondered why Chinook didn't have a cable TV connector either. Now I know, can't help but wonder what happened. I don't see any wires/cables hanging around under the couch, I'll have to explore more later.
I do like the idea of adding a solar connector there.
Thanks again

The phone and cable wires go from the receptacle on the driver side to the inside via the space between the fiberglass and the inside panel, and they are not long enough to dangle much. You should not be able to find them under the couch/sofa. Maybe they just cut the wiring off somewhere along the route?
