Which BTU to choose?

[Tabasco]

So after thumbing through pages of info I did not find the answer I am looking for.
What BTU should you choose? I understand that it is a square footage equatio, but what is the formula for a silver twinkie?
This is is a 24 footer BTW...

For what? Air conditioner or the furnace?

The choice will probably narrow down to what is available, and what you are doing with your rig.

Air conditioner.

We got rid of the furnace all together, btw. Just need to replace the AC unit soon, the compressor is acting up.

13,500 would probably do it OK, but you'd like a 15,000 better in hot weather.

Get at least a 15,000 BTU

All RV air conditioners are noisy. The 13,500 BTU unit will run longer - which may actually be less irritating when you're asleep than having the bigger unit cycling on and off, waking you every time it starts up. A unit that is not constantly switching on and off may also last longer. OTOH a 15,000 unit on a 100 degree day will cool faster and perhaps to a lower temp than a 13,500 can achieve. Where you camp is important too. In Southern TX - go for the bigger one, in the hills or woods where temperatures are more moderate, the smaller one makes sense.

Personally - talk to someone like Lewster and find out which units have the best durability and lowest noise level, and best ability to direct air into the both ends of the camper - then choose that brand and size recommended.
