Which 120V wire?

Hi, I am wanting to replace all the 120V wiring in my '61 Safari while I have the inside skins out. I don't plan on being hooked up to shore power all that much and I never plan to have an air conditioner. Someday I would like to have a microwave, hybrid refrigerator, maybe a TV.



Given this, is just a regular 3-prong receptacle adequate for the shore power inlet? 15A I think it's called?



I picked up some Cerrowire indoor 12-2 NM-B w ground at Home Depot. Is this the right wire for my needs?



Thanks!
