Well, I have something to admit here. DH and I have struggled with backing in our approximately 40 ft 5th wheel. It has taken up to over an hour to get it in our spot at the storage facility. Last time we had to do it, the batteries on the walkie talkies were dead. So we decided to use our cel phones. I've got to tell you, I was in fear for my life when I tried to turn mine on and had to tell DH that it was dead too. He just looked at me and said "Well just yell if I'm going to hit the RV on either side of our spot. Did that and it worked so much better. Then again did the same thing. He looked on the driver's side while backing up, I yelled while positioned on the passenger side if he got too close to that rv or the fence on the border of our spot. Took 10 minutes to back up and park, another 15 to unblock, lock up and take off. Best personal time ever. So my only advice is that everybody needs to work out their own system. Best of wishes to you. And listen to those more experienced than us, watch videos, maybe take some classes if they are available in your area and have some good insurance, just in case. And have fun, like we are after our first 4 outings!!
