Biggest thing to remember is to make wide turns, a fiver tracks inside the trucks track. My wife and I watched a fifth wheel take out a stop sign this weekend while camping. He not only hit it once but managed to back up and hit a second time. The third time he went wide and made it. Not sure what damage was done to his fiver as he never stopped to look.
Backing up, pull farther foward than you think and once it starts to turn start correcting because it turns quick.
Find a big parking lot and practice, practice, practice. We took ours out several weekends in different areas to learn how to pull ours. Good luck.
