Dometic VT24 on label. I think it's the 211. Have a 211 manual that came with trailer.
It's a three way, but never was hooked up on 12v, so I don't know if it works on 12v or not.
Did work on gas and 110v when I pulled it out two years ago or so to put the air conditioner in. Needs a good cleaning and replacement front panel. It's kind of a warped plastic panel about 1/8 in thick. I though of using Luan for a panel before I pulled it.
Anyway we are cleaning garage out and wife says we can't take it with us when we move next spring.
Pick up only, sorry I don't need the hassle of trying to find a way to ship it.
It will be here til next spring so if you're passing through or know of someone who could pick it up for you let me know and it's yours.
Just send me a PM.
