Jim & Kim,
 
I had one of these systems in my Syncro Westfalia. It was a great = option once I had the unit serviced. They can heat the coolant up to operating temperature in about 15min. They are also are programmable for two = preset times and will come on and heat up the interior of the van before you even get = in it to start in the morning.
The are really great for winter camping, and will maintain the = interior temperature while the van is parked and the motor is turned off.
Go to a facility that = services these units. They are called fuel fired coolant pre-heaters. They are made by = Webatso. They are very common on big rigs  that are out west and those that = go up north. The web sits is
<http://www.webasto.com> I would = strongly suggest that you go to facility that services these heaters. There are = not common and not a lot of people are familiar with how they work and how = to service them.
 
Cheers
