My question is more about safety.
PROBLEM :
I have found trying to charge a house battery (deep cycle/Marine) using the vehicle's alternator and an isolation transformer to be less than ideal. In a nutshell the alternator sees both batteries hooked in parallel as one battery. However they are different. One is meant to be slowly discharged and the starting battery quickly discharged. So the alternator doesn't deliver the proper amount of juice to the batteries because it sees the starting battery as being full.

CURRENT SETUP :
I have solved this problem (see above) "cheaply" but running the battery to a 120AC inverter, then a trickle charger (https://www.batteryminders.com/1510-12-volt-maintenance-charger-desfulator-with-warranty) , and the 12VDC output of the trickle charger to the house battery inside my Jeep Wrangler. This model trickle charger hits the house battery with a higher voltage to wake it up and accept the charge much better than a straight DC charge from the battery isolator. Once the battery is topped off, the trickle charger continues to desulfate the battery. it seems to charge it in a fraction of the time that the DC method does, and doesn't really cost much.
FUTURE:
I'm wanting to get an off road trailer with solar, and battery setup on it, moving the house battery(s) from the Jeep to the trailer. I want to charge while driving using the same AC method as I do with currently. AC makes the trip/distance much better than DC with much less loss and cost in wire gauge. The AC inverter source will be treated like shore power while driving
QUESTION :
This is a safety question. AC can be deadly, keeping this in mind. Hooking up a run (25' 10/3 extension cord) from the Jeep to the trailer, securing it, breakers/fuse/GFCI etc. ,
Can anybody see a problem with this while driving?
thanks in advance.
