All done and tested
I sweated buckets today finishing the installation in 97 degree record-breaking heat. Everything works as advertised. I forgot the camera today, but I'll take some photos next time I go to the trailer.
I made one change in my earlier plans. The propane detector should be hot at all times so I first thought of using a "Y" of diodes to power it from whichever battery had the highest charge. Instead, I installed a SPDT toggle that allows me to choose which battery powers the detector or turn it temporarily off. The off option is just a by-product of a center-off SPDT switch I happened to have in the workshop.
I also wired in permanently the 750 watt inverter that stows under the couch end. I wired the inverter to the common of the battery switch and to the ground block which, thankfully, had one free hole.
