I have a 2011 Chevy Silverado 1500WT v6. It has a 7 blade connector, one blade provides 12v. I don't yet know if that's constant, or only when the ignition is on. Additionally, it's my understanding the newer vehicles, I believe mine included, has some sort of load sensing charge controller stuff. Essentially the alternator has three levels of charge, and it only bumps up to a specific level of charge based on sensing drain. I'm not sure if re-charging my house battery will work off that 12v blade connection without the smart sensing stuff?
I understand I need a breaker box for 120vac shore.
I understand I need a fuse box for 12vdc.
And now I'm lost.
Scenario:
1) While driving starting battery should charge house battery
2) When parked support shore power. Two 120vac outlets, charge house battery, power 12vdc accessories (can't they continue to pull from house battery?)
3) When parked support battery power. Only power 12vdc accessories (no need to convert to 120vac).
Which leaves me with another question, what do I need to buy to protect the battery/wiring/yadda if someone starts the truck, thus charging the house battery from 12vdc while still connected to shore power? In my mind a simple switch labeled "Shore power/Battery power" could be flipped, is that all there is to it?
Links to products on amazon/websites appreciated. Max load would be a ceramic heater, or an electric blanket (not both) and charging a laptop plus two cell phones at one time.
