Heated Travel

I have heard of running the roof air conditioner off the generator while traveling. Is it safe to run the furnace off the generator while traveling? We travel to Florida every March and sometimes the first morning is quite cold, even after preheating the coach for several hours before leaving. The dash heater could not keep up with the heat loss while traveling. Riding in an oversized icebox isn't much fun.

Bill, I’m a little confused by your question. Typically the RV furnace is powered by 12-volt DC, whereby the fan, thermostat and internal components all run off the auxiliary battery. There’s no reason to run the generator since AC electricity is not needed. You will, however, find some experts who say you should not travel with an open LP container. This is a debatable discussion I won't go into here. However, I do believe in periodic LP leak tests to ensure the integrity of the LP system. If you are sure no LP leaks exist and you have adequate ventilation, running the furnace while traveling is doable. While driving the engine alternator will continue to charge the battery systems so there’s no danger of draining the battery by using the furnace. You should be good to go as is!
