A conversion for 5000 btu is about 1500 watts which is around 13 amps. This conversion is whether you use the strip heater or an electric space heater.

This is correct, but why not use it to temper the whole camper instead of just one area this will come out all your ceiling vents. You can find the info at the axcel site who is the distributor and supplies for your a/c and suburban products. If you can't find it let me know I will send you a link. I have a suburban A/C. Pretty simple installation. And by the Merry Christmas to you and your family.......

Oh, I agree on "distributing" the heat aspect of using the central air. Actually that is why you can operate the air conditioner fan when the furnace comes on; heat rises so you have the ability to move the air around through the RV using the air conditioner fan.
Our coach lacks furnace diffusers in the front 1/4 area and rear 1/4 but the air conditioner has diffusers throughout.

Merry Christmas to you and yours!

Heat pump--(yes heat pump, not just electric coil in AC). Advantages, runs on electric so (at a camp site) it costs you nothing. Air distributed through ceiling ducts. Disadvantage--only effective down to about 35 degrees. Warm air is not circulated into air under floor or compartments to keep holding tanks and pipes warm.

Furnace--Runs on 12 volt (for fan and controls) and propane for heat. Advantages--heats with much warmer air than heat pump, through ducts generally at floor level. Can be used when no electric is available (although uses up battery power rather quickly). Heats space where pipes and tanks are under floor to help prevent freezing. Disadvantage--uses your propane.

If I have electric available and outside temperature is 40 or above, I use heat pump. Switch to furnace in lower temperatures or when no electric (of course you could run generator for electric).

After 2 motor homes with heat pumps, we decided they really weren't worth the money for how we camp. We've always preferred the heat strips since they don't care what the temp is. An alternative we've used on other units is 2 tower heaters. Put one under each AC intake, or reasonably close since heat rises, run the AC fan only on low and you get the same or similar result as the heat strip. Doing this we've always had success keeping everything warm. However in addition to that set up, we always did set the furnace around 50 degrees, just in case.

I agree with all, but it is proven fact that if you temper your air in the return it will come out alot warmer. The point is that you can run a 1500 watt heater and the heat strip together being they are on different circuit. Try plugging in 2 stand alone heaters it will trip a breaker every time. If you do not temper the air coming out of the registers all you are going to do is get a cold blast of air about 10 degrees cooler then the units temp inside. It's the product of air movement. The air is moving to fast to hold any real BTU's. In the 80's people use to try and install a return air above the firer place in there homes, I don't even remember how many my company installed even through we recommended against it. But the customer was always right and we explained it but they still wanted done. So we did it and not one person thought that it helped that I know of. You just lose that btu by the movement of air speed (cfm). That's why a heat strip is better. If you are going to do that set up. it will help temper the air before it hits the duct work
