I'm selling a used and functional Webasto Heater. It's the gasoline version, Air Top STC 2000. It was purchased new and installed in my van in 2017. It worked great for me, but I found in cold temps, the location I installed it (under the passenger seat -- see photo), I couldn't keep my water pump warm enough (it's way in the back of the extended length van under the bed). So I ended up installing a second, Propex heater under my bed. Anyways, I stopped using/needing this so I figured I'd sell it while it's still in good working condition and in demand.
I rebuilt it once due to carbon buildup and haven't used it much since then. You'd probably be good to go for a long time without that update, but for $60 you can get a new burner, which might not be a bad idea while it's accessible.
I'm selling only what you see here. It's the main unit, the attached wiring harness for the fuel pump, and a custom stainless steel cover that helped me for sealing it to the van floor. You can see this cover in one of the photos.
You'd need to buy the assembly kit to get the necessary parts to install this unless you already have them. Here's a link to that new burner: https://ebay.us/m/MF2Fqc
