The DW and I always use walkie-talkies because without them it is too easy to start yelling instructions and blood pressures and temperatures go up. That is what I have heard anyway...
We also developed an short language for us that is simple and easily understood. When backing up she will tell me to "turn more" or "turn less", which eliminates who's right and left we are discussing when backing up. Of course "stop" and "come on back" are also used. Anything else that happens or something special that demands an explanation, we will stop and both go look so we are on the same page. Have no problem and everyone is still speaking when we get parked!
BTW - my brother and his DW don't use walkies and may not speak for about an hour after parking.
Geez...isn't camping fun?

"Happiness? A good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle."
