Total Rebuild of a 1979 Dodge Class C

I do not know if they make a true sine wave inverter that small and a lot of the new appliances do not like to run for very long or at all on a modified sine wave inverter which most of the 300 watt units are. The older reefers with the old mechanical controls would work, but the newer ones with the electronic circuit boards are more problematic. I would try it before you need it.
