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
Or,
Here we go!!! Hard wire this beast to an outlet and your set! ......... Oh, never mind the Links are not working correctly.
Ref my first link posted.
my second idea, with a hard wired outlet.
