"Dry" camp question

[mike4947]

Another dealer that's talking out his backside, because his mouth knows better.

In LARGE absorption fridges, yes, they only run on 120 volt & porpane. But on fridges under 5 CF 3way (12 volt, 120 volt, propane) is still the standard.
It has to do with BTU's and what energy it takes to move them.
12 volt is designed only for traveling as it's BTU output is normally around 1/2 the 120 volt and propane output.
On the average it takes about 1 amp per 30 BTU's. Your avarage 2.4 CF fridge is rated at apx 300 BTU's in 12 volt mode so it's draw is apx 10 amps. Since a 10 CF fridge would require about 700 btu's in the same mode that would mean an apx draw of 24 amps. Even with a good 12 volt aux line from the TV that would be a major draw and most likely the fridge would deplete the trailer battery during travel.

That is too bad.  I run my fridge on DC 12 volt power when towing.  I would be a pain to stop at the tunnels that require you to have the propane turned off in order to go through them.  It must be safer to tow with the fridge on electric or they wouldn't have that requirement for the tunnels.
 
The 12 volt line from my TV to the trailer is off when the TV is turned off.

That could be easily remedied by using an inverter to run your fridge on 110v while towing . That is, assuming you have a  heavy 12v connection from TV to trailer.

I wouldn't want to change it.  The way it is now, I will not drain the TV battery by accident.

Ya, sorry, I didn't really mean you, as in you.

What I meant was, if a person was to purchase a new trailer that had a 110v/propane fridge, an inverter could solve the problem of running the fridge on propane while driving.......................Shwew :p ...........glad I got that cleared up.
