All I can say is there is some good advice here, I have had three fifth wheels since 2005, an 18.5 then a 22 foot now a 24.5 and I have never practised, it has always been hook up go on holidays, get to site back in, then go home at end of holiday and back in to a very tight driveway in our narrow alley with hedges in the way, then repeat the next year, so I learn each time basically two times a year, not the best way as I will never be good at it, but at least I have learned to be calmer about it.
We actually had almost two years during this time where it never moved, so all advice here is good, but yes if you can get in practise I would.
