new to rving, resorting camper

The Rv trailers are all built to run on both 12VDC and 120VAC to satisfy every one's style of camping...

This is what a typical 30A Trailer wiring configuration looks like. As you can see there is alot of 12V DC built into a typical RV Trailer setup..

I don't think I would ever completely take away the DC operational status...

If you are still planning to tow your RV down the public roads you will still need to satisfy the DOT requirement of having an active battery setup to operate your trailer Electric Brakes in the event your trailer becomes disconnected from your truck while being towed over public roads. This is an enforceable State DOT Safety requirement...

I guess not having 12VDC circuits would mean your RV trailer would become a TRAILER PARK trailer haha...

Maybe never on the road but setup permanently somewhere and never be towed anywhere???

If you don't have a battery bank and never camp without the generator or shore power. Then no you don't. I bet you will need at least one good battery for 12v power. The question is do you have just an inverter or a converter/inverter that also charges the battery?
