Hello, I am a food truck owner and I recently had a situation which made me rethink my power needs for my kitchen on the food truck. I have a 2001 Workhorse forward control Stepvan and I wanted to run an alternator, batteries, and an inverter setup INDEPENDENT of the trucks own alternator and electrical system. I first thought of using a high capacity alternator and just running everything off of that because I was reading about how difficult it may be to couple two alternators together, however the best option for my needs would be to have two separate electrical systems. I am hoping someone can help me figure out the best and safest course of action. Thank you for reading and I thank you in advance for any advice.
