The wife and I use Walkie Talkies when we are checking lights, etc. on the motor home and toad prior to departure and also when backing into a site or the storage building at home. Works SO MUCH better than hand signals. We have also used them when we are traveling in separate vehicles to talk. We have also used them when traveling in car clubs. Don't expect a 23 mile coverage. But for our use I will always have a pair to use as noted above.
