When I was thinking about buying a caravan, one of the aspects I was nervous about was reversing with the caravan. At the time, my car didn't even have a tow bar, so I couldn't practice with a trailer.
After purchasing the caravan, I explained to the campground receptionist at the first place that I had literally JUST bought the caravan and would appreciate an easy site. She found a spot where I could drive straight in - perfect. I happily procrastinated about learning how to reverse for a while longer.
It's really just practicing. The second campground I stayed at, there was no-one watching, so I gave it a good go and started to understand how the caravan moved. I've become competent and have been able to reverse into all the sites so far... even if it takes a couple of goes.
I'm not perfect yet... but I'll get there. Practice, practice, practice.
