I am thinking of installing a Webasto cabin heater, it also acts as a block heater. Does anyone have one that they can give me an opinion? I like the
idea that it acts as a block heater and cabin heater, as I live in New England
and use my truck to go snowmobiling up north.

I had a Webasto in my 04.5 Dodge - loved it. I have an Espar in my 06 GMC - don't like it half as much as the Webasto...

Either one is worth the money in my books. I use my truck for snowmobiling in the mountains, and I set the timer for an hour before when I expect to be back at the truck - works like a charm...
