Spotter for backing your camper up

I was over at the Love Your RV website today and found these great hand signals
for your spotter to use and I think we will implement them ourselves in conjunction
with our hand held radios.

Our Hand Signals for the Spotter
    Stop – Hand up palm facing  the driver
    Direction – Arm straight out pointing left or right
    Pull Forward – Pointing motion straight at the driver
    Trailer needs more jack – Arms up in 90 degree angle from each other
    Thumbs up – looking good, keep going
    Driver points up – spotter checks for any possible high obstacles

My thanks to Ray for sharing
