Hello, I bought a completely gutted camper trailer had have been rebuilding it. I am currently installing a kitchen. I will have small, two burner camp-style gas range. I understand it is code to have a range hood for it? Does that need to be ducted or can I use a non-ducted hood? Also, there is no previous wiring for a hood, but there is a non-grounded outlet nearby. Am I able to have it wired into that circuit easily?
