Hey LaMonte! The Xtreme Heaters Electric Space Heater # XH74FR has 750-watt and 1,500-watt settings, so your 3,000-watt inverter will have enough capacity to run it. It can provide good heat for a smaller truck cab, although how well it works will depend on the size of your cab and how well it's insulated.

The concern is running it overnight without draining your batteries. Even on the 750-watt setting, this heater draws a significant amount of power, and two typical truck batteries won't have enough capacity to run it all night without risking a dead battery. I really wouldn't recommend running it overnight from your starting batteries. You would need a separate battery bank with sufficient capacity or another power source for that kind of use.

Are you trying to keep the cab warm throughout the night while you sleep, or just warm it up before you get going in the morning?
