POSTING IN ALL CAPS

EDMATLOCK-

I think your post just summed up VERY ELOQUENTLY what could happen if someone drove with propane on . . .

Don't worry . . . keep posting!!!!!



P.S. I think ALL posts are relevent whether they "SAY" something or not. Please let's not trash each other. We are all part of one family . . . let's be respectful.

Thanks for using lower case. It is much more pleasureable to read your post.

However, what you described has nothing to do with travelling with the refrigerator on. It could just as well have happened in the middle of the night with everyone sound asleep in the MH.

Current propane equipment has provision for blocking flow to a burst line and would probably have prevented the total catastrophie. Amonia explosions are quite rare, but are one of the small risks of using adsorption refrigerators.

Just a friendly note, some people consider that you are yelling, writing in capital letters. Just one of those unwritten cyber rules.

John,

I disagree with your statement: "However, what you described has nothing to do with travelling with the refrigerator on."

As I understand it, towing with the refrigerator off, or in AC or DC mode would have prevented the accident since there would not have been an ignition source for the ammonia gas.

Pahaska -

Well, I disagree with HOW you reprimanded EDMATLOCK. All you could have done is ask him for specifics, clarification and details IN A NICE WAY. You have done nothing to advance the subject matter yourself by reprimanding Ed - all you did was make someone feel bad.

And who cares about cyber "rules" as long as we are being respectful? So what if someone writes in all caps? What - does it hurt the eyes? If anything, it makes it easier to see than the lowercase letters! (I guess I am "shouting" since I wrote that exclamation point -?).

As long as everyone is RESPECTFUL, that is ALL that matters.

FYI - I totally agree with Edie.

You missed my point entirely. What I said was that the ammonia leak could just as well have happened when standing still, say in the middle of the night. The fact that the MH was underway was irrevelant. The risk is inherent in an amonia adsorption refrigerator.

There was another recent post where an owner smelled ammonia while hooked up. He ran outside and jerked the power cable. The refrigerator, lacking 120v power, automatically switched over to gas, as it is designed to do, and caused a fire.

Let's agree to disagree. I feel the post was entirely relevant in a discussion regarding refrigerator modes of use.

I will admit, I usually agree with you and admire your high quality posts. But I disagree with every post you made to this thread today.

No problem. Reasonable people often disagree.

Let me put it another way, though. I often dry camp overnight at a truck stop. Many times at music festivals, I dry camp for close to a week at a time. There are many posts here where people are installing solar so that they can dry camp for very extended periods, weeks or more. During all these periods, the propane is turned on and the refrigerator is running in propane mode. The risk of explosion/fire is just as present during these periods and the periods are typically much longer. Longer period = longer risk. In addition, during a portion of these periods people are asleep in the MH or trailer.

Should we tell everyone to never use the refrigerator on propane? I don't think so. Almost everyone would agree that the risk is almost vanishingly small.

Basically, there is nothing in the wheels going around that modifies the risk. In fact, the increased airflow that comes with travel might possibly prevent the concentration of amonia fumes from reaching explosive concentration and prevent an explosion that might have otherwise occurred.

Disadvantage of 12 volt operation

There is usualy a negative side to most things. Typically, operating on 12 volts, will draw 23 to 25 amperes from the coach batteries. If you have been dry camping all of your batteries will need a good charge and this will not happen if the refrigerator is operating on 12 volts. Further if one or more of the coach batteries has been discharged into a deep cycle you can end up with a destroyed battery. All three-way fridges have an automatic circuit which disconnects the box from 12 volts if the ignition key is turned off.
On the WBCCI Newfoundland trip you have to turn off the propane for from 6 to 17 hours depending on which ferry is being used. As long as the box is not opened the fridge will maintain a cold environment. Of course Newfoundland is not 110 degree in the summer.
What to do? I use the (1) turn off the fridge completely and don't open the box; (2) run the fridge on propane while driving; and (3) run the generator for 110 AC operation depending on the circumstances [low batteries, getting gas, ferry ride, short trip, hot summer temps etc.].

A/S Refrigerator

I have read all the posts in this regard with a great deal of interest. I can see both viewpoints about operating the Frig underway on the raod, but according to MY AIRSTREAM MANUAL.
There are safety locks and relays which switch operations from gas to 12V to 110, depending on the situation automatically.
There is no way the flame (gas) is on when you are on 12V, and there is even a 30 minute delay to returning to gas when the 12V is off. Apparently, from the way the A/S Manuial is written ( at least for Motor homes) it is intended that the Frig be placed in service while travelling. Of course there is no justification for running with the Hot Water Heater on while underway, or while fueling. But the A/S refrigerator system is absolutely safe while fueling and travelling UNLESS someone has altered the system installed by Airstream. I agree that for TOTAL safety, only closing the valve on the LPG tank would be totally safe, but 3=way refrig are manufactured and installed for highway use while travelling, and apparently, A/S intended that they be used that way, and their Manuals for Motorhomes reflect that position.

The latest issue of Trailer Life (Dec.'02, page 74) has a Q&A about this issue. According to them, driving with the refrigerator on LPG is completely safe and no state has any laws prohibiting it.

This is contrary to what I have been told, but is a welcome answer that will make my traveling life less stressful. I'll now travel with the refrig. on LPG when I need it.
