Solar and Charger into one?
I am modifying my cargo trailer to be more like a camper, and dug up some old stuff for it. I have a modern MPPT solar controller for the 100 watt (soon to be 200w). Two golf cart batteries. I ha...

Thanks, but that was just for fun. I owned this in my first motorhome and used it onboard that for 15 years. no complaints.
I have a very expensive camper in the drive, so this cargo trailer project is not going to be the end-all of technology. I want it to work well.
Back then, about 2001, I had a 12x14 solar panel that was only 5 watts. I wired it straight into the battery, all 18 volts, and it did a great job keeping the battery alive while in storage. I never had to charge it. Today I have a 12x14 inch 20 watt solar panel to keep my cargo trailer brake battery alive but have graduated to an MPPT controller. It also powers a few LED lights and the exhaust fan. It being the battery. I think I will leave that solar/battery system in place just for the brake battery and introduce the RV batteries for everything else. That makes no sense to not use the camper batteries, but I have no other use for a small solar panel and exit battery.
Did you know that in most states you need to carry either flares or reflective triangles when towing a trailer? I have the triangles, and they take up space.
