Air C/Heat P Dometic instead of Furnace?

We are redoing a gutted 1960 24 ft Tradewind and can you tell me?

Can a Dometic 651816 651816.CXX1C0 Penguin HP Heat Pump 15k 15,000 BTU Air Conditioner be used for cooling and heating our trailer ($1400)?

OR would it be better to use a furnace (Suburban NT-30SP Electronic Ignition Ducted $543) with an 15,000 BTU air conditioner (around 1200)? If so both would be ducted, right?

I'm TRYING TO PUT TOGETHER A COST SHEET AND FIGURE OUT EVERYTHING I NEED. WOW. I didn't realize.

Your input is appreciated! I can't believe how much there is to learn. THANK YOU FORUM!

The heat pump used in RVs does not work much below 40 degrees. It freezes up.

If you've got your trailer gutted and have room to work, I would recommend getting an Atwood or Suburban furnace and adding a CheapHeat to it for heating with either propane or electric (full disclosure, my dad owns the company that makes CheapHeat). The biggest problem with retrofitting it to finished trailers is space. It tends to be easy with big 5th wheels since they have basements, but harder in travel trailers. I put one on my 2014 25EB but needed to add an extension cabinet to hide it. When in CheapHeat (electric) mode, the fan is slowed down so makes the furnace super quiet. rvcomfortsystems.com

Actual trailer useage?

How do you plan to use the trailer?

If planning a lot of boondocking, then the furnace, for should be included - maybe.

If your planned use requires an AC, get a Heat Pump model - the footprint of a heat pump/AC is the same as a non HP model.

Unless you anticipate camping consistently in sub freezing temperatures, a small catalytic heater could possibly be substituted for a furnace, making the furnace area available for storage.

I will respectfully disagree with this statement. I have a '97 excella with a 13.5K heat pump that we have in temps down to 25 degrees. Yes, it will go through a defrost cycle now and then-just like the one in my house. We use an oscillating ceramic tower heater in the living room and a small one in the bedroom to supplement. We are comfy. Really have not had a need to run furnace.

As stated by others, your individual use will determine your choice.

I like my heat pump because the fan does not blow constantly like a straight A/C unit. Ig you had a straight A/C unit with a heat strip you would need the furnace as the heat strip is worthless. You will get more heat out of a ceramic heater. Just my two cents worth here.

If you do go with a heat pump, by all means go with a 15K.

Should mine need replacing, I will be going to 15K.

I have heat pumps and a furnace. In general, heat pumps aren't suitable as a sole source of heat because:

1) Heat pumps are loud
2) Heat pumps require shore (120v) power, which isn't always available
3) There is a temperature below which they do not provide sufficient heat.

The exact temperature at which a heat pump won't work effectively depends on the heat pump and the trailer, however, with most installations it's somewhere between 25 and 40 degrees. A properly sized furnace should work (i.e. keep the trailer at 68 degrees) down to about -10.
