Smallest cheap (expensive) heat is 1800 watts iirc. That means it can't be used on a 15 amp-shore power.
Sizes are 1,800, 3,750 and 5,000 watts

Very pricey and requires many hours to install. No fail over to the propane furnace.
Cheap Heat is one package, with different settings, there is now a add on unit that will auto switch from 30 amp 120 volt to 50 and 220 volt, thinking of getting as would save me a 20 amp breaker, and 20 minutes to change wiring.
The only time consuming part of my install was installing the gas/electric switch next to the t-stat, required locating a spot between the FW and Black tanks to bring the cable to the underbelly.
To me the auto switch over is a no big deal to me, get out of bed flick switch, get back in bed.
