The year of the camper suggest the isolator is the older shure power. That one protects the starter battery and prevents charging the house batteries when the house batteries are lower than the voltage is required.
Or just making intermittent contact. Considering that neither charging source is working properly that sounds more likely to me.Can't help from wondering if there are fuses or hidden ones either the positive or negative wires coming off of the batteries that are blown.
My 2004 had no camper battery hence no isolator at all.The year of the camper suggest the isolator is the older shure power. That one protects the starter battery and prevents charging the house batteries when the house batteries are lower than the voltage is required.
Consider getting one or two rechargeable bug zappers to put in the camper prior to bed.We did this same bird count last year and the mosquitoes weren't too bad, but it was a few weeks earlier in the season. I'll look into the Thermacell. I've heard others here say it's effective.
Yes. That's a little strange. One of those numbers had to be bad (or intermittent?) The solution for the truck charging issue is more $$$ being thrown. Either fatter wires, or a DCDC charger, or both.Weird that one tech got 19 volts from the panels and now its under 9. Glad you got it all fixed.
I still believe that the truck was not changing was due to the camper batteries were too low for the Shure Power isolator to send charge to them. Designed to protect the truck battery.Yes.

The Blue Sea ACR is the best direct replacement, a good Victron DCDC is the best upgrade. With all three though, the real problem is the tiny wiring FWC installed from the truck battery back. It's simply too small to carry reliable, functional current for charging a house battery bank. Lithium or lead.Others can chime in and get technical and suggest a replacement for the 1314A unit.
It seems most likely that the original panel had a bad/intermittent internal connection. When we replaced the failed panel, we also had to replace the original Zamp PWM controller with a Victron MPPT to handle the increase in PV voltage with the new solar array.Yay! Problem solved! Patching up a old and failing system is not worth it, IMHO. Yes, time to move on. I am sure you know to bring plenty of mosquito repellant with you to summer lake. The Thermacell creates a small bug free zone you can relax in peace within.
