Gas or Electric

I don't know about Jayco Super Lite's. If the heater vents down into your underfloor then you definitely do not want to use portables. If it does not vent down then it wouldn't matter.

Good idea. Or, run a separate extension cord into the RV and run the heaters from it. I have a 25' 12 guage cord that I plug into the 20 amp outlet that most campground boxes have and pass it by a slide seal. That way the heater is on its own circuit.

It depends on where the water lines in your Jayco are located.

Pianotuna seems to have it figured out the best.

When I camped in temps in the teens I used 2 1500 watt electric heaters inside the MH and a 750 watt one in the basement area to keep the plumbing from freezing. I also did not use water hookups but drew water from the tank using the water pump.

Hi,

Replace the return air grill for the furnace with dual window fans. That allows me to heat 100% electrically at -37 c (-34 f).

Running the propane heater may be cheaper if you are paying for electricity. If power is included in the site rental then use as much electric heat as you can.

There was a post a few days ago where they were supplementing their furnace heat with an electric heater and pipes froze. An electric heater can effect the furnace thermostat i.e. making the RV to appear warmer thus not turning on the furnace in below freezing weather. You do need to keep your basement above freezing. I use an indoor outdoor thermometer and monitor my wet bay temp.

It's okay to supplement your gas heater with an electric heater.
Many do it, myself included, when on shore power. It doesn't hurt anything.

Electric down to about 25° and then you need to start heating the basement areas to keep the water lines from freezing if it stays below 25 for several hours. This could be 100 W bulb if all of your water lines are in one area. Unhook and drain your outside water line and use your water tank when it gets below 30.

Most campers I know run an electric heater when ever they are connected to shore power and run their gas furnace along with it when temperatures drop to a point where the electric heater alone can not the keep up.
