Does anyone know what the power draw (watts) is on the Duramax engine heater? I want to use a timer to turn the heater on at the desired time & I need to know how robust a timer I should buy.

If its a standard three prong plug, they are limited to 15 amps. (~1600-1800 watts) and from what I hear, they pull every last watt they can. For the sake of saving the timer, I would have the timer triger a relay with a contact rating of 20 amps minimum. Its something I have always wanted to build, but never had a use for such a "heavy duty" timer.
Get one that's rated for an air conditioner. May be hard to find this time of year though.
As Trey pointed out, three-prong limits it to 15 amp max. You can purchase "heavy duty" appliance timers rated up to 15 amp -- make sure it's three-prong, don't try to rig up two-prong with a grounding wire....
This might do the trick

I am still not a fan of the "tight tollerences" that are used these days in terms of what will technically fit through a wire. Most extention cords are not big enough to run at the posted load. We have a little Black and Decker leaf blower that I use and the extention cord gets warm after a few minutes of use. Not a good sign.
