Following up on our charging issue. I replaced the auxiliary start solenoid with a Redarc Electronics dual sensing smart start battery isolator 12v 200A. I purchased it from Etrailer, but it is also on Amazon. This isolator is good for marine and RV applications. I am currently traveling and the problem appears to be fixed.
This is an upgrade to the OEM auxiliary start switch. This battery isolator allows the house battery charger to also charge the chassis batteries. Further information can be found on the internet and it does work as described. This was an easy upgrade. I was able to DIY it. Just take the old one out and put the new one in it's place.
I hope this information is helpful to you.
