Question:
I have a 1940 GMC truck and I would like to have more heat in the cab for winter. It has a 12V lighter. I have a CD12V to 110V conveerter with plug in. I am wondering if this will power the 900W version of your heater or would there be issues. Should I just go with the 150W 12V version? I am worried this will not be enough heat. I like putting it away in summer so not inclined to wire it up to battery. Any advice is appreciated.

You'd have to check the wattage of your inverter to determine if it could power the Kat's Heaters Vehicle Interior Heater # KH37100 that you referenced. If it's rated for 900 watts or more this would work but if it's lower rated it would not.
Otherwise we have a 12 volt heater that could be wired directly to your battery with the part # RA3501 which puts out a decent amount of heat.
