My Ram 3500 only has a single alternator so I am using a Victron 30 amp dc to dc converter. In the truck I installed a contractor and circuit breaker that I can turn on the dc to dc converter with one of the dash mounted switches. This last summer I typically waited until we were on our way before turning it on giving the truck a chance to recharge the battery from starting reducing the load on the single alternator. It has worked really well. In the truck bed I have a dealer anderson plug (120amp) for quick plugging in. I went with that large of a connector due to voltage drop from the front of the truck all the way to the garage where the dc to dc converter is. One of the wire sized calculators I used stated for 12vdc, running 25’ and 30 amps you need #1 wire due voltage drop.
