Just a note about Canadian Tire (a.k.a. China Tire) Inverters. Their
450 Watt model is suspect. I have gone through 3 of them, all
replaced under warranty as the first 2 each quit in less than 30
days. I now also carry a spare by Cobra and I've got my fingers
crossed.
        My very first Inverter (I forget the brand) was a 300 Watt
and it ran the Dometic for two years without a problem until I cooked
it by plugging into a AC outlet before unplugging the inverter.
Bummer...
