"Termination skills", that's funny. All I did was bolt the cables to the components and slip the covers over the connections. The terminals were already crimped to the #2 welding cable. I appreciate the positive reinforcement and taking the time to comment, though. Unless it was sarcasm, in which case it's hilarious. I did attach the gold-plated terminal to the #8, years ago. It was re-purposed from an old car stereo install. I also threw on a fresh layer of shrink tube.
I bought a transfer switch from DonRowe, too, but I haven't installed it, yet. The plan is to tie into the existing outlet circuit at the camper's breaker panel. For now, an extension cord will be used to power our devices. I'm sure I'll get tired of tripping over it in short order, but I have other priorities between now and our next departure. Our situation requires remote storage, so, sometimes it can be a hassle performing modifications.
In a perfect World, with all the space that's available in a TC (LOL), I would/should have placed the breaker closer to the battery connection, but this spot makes it easily accessible from inside the coach, without being a contortionist. It's ignition protected, and I think I could have mounted it in the battery box, but I like the ability of being able to use the breaker as a disconnect to reduce parasitic draw without going outside. Speaking of space, the inverter is supposed to be mounted horizontally. I couldn't find a suitable place for that orientation. I'm not sure why it's spec'ed to mount horizontally for RV applications, but not other uses. Maybe, it'll shake itself apart. We'll see. I hope I didn't break too many rules on the install. Hmmmm. I wonder what I did with that fire extinguisher I bought 8 years ago?
