"Wow those are awesome!!!! I might look into that! About how much do they want for one? "
Not really.
Probably way less over your way, seems to be that way with most things.
I paid the equivalent of 4 grand for mine.
It has a timer, that will allow you to set it to start in the morning, so you come out to a warm car, same for afternoon, when you are going home. It has 4 settings, so when we are logging and eat at fixed times, the truck is always warm for us.
Also, you can call it up by phone and change the setting or start it up.
When we are working a big tree and lunch is drawing near, someone on the ground will either walk to the truck and turn it on manually or if the truck is parked far away, call it.
Then we have a warm place to sit and eat.
Never cold starting your engine makes it last a lot longer.
I got 500,000 kilometers out of my last VW truck before rust ate it up.
Expensive, yes, but once you've had one, there is no going back.
