UPDATE --- Converter/charger issue?

I bought a Powermax 55 Amp 4 stage from Amazon to replace the Iota 45 Amp with IQ4 dongle. Believe it or not, the 55 Amp unit was $30 LESS than their 45 Amp one. I didn't wan to go with the 75 or 100 Amp (even though my two 6V golf cart batteries can likely take the current) because my RV wiring from the rear mounted converter/charger to the front mounted battery bank isn't very heavy gauge wire. I suspect it was spec'd by the engineers at Jayco to carry 45 Amps max on a single 12V battery so I might already be pushing it with a 55 Amp unit.

I use a Firman 3300w/3000w inverter generator for the dry camping we do. 90% of the time we have zero hook ups when camping in the Canadian Rockies.
