Don't know of any schools. But what my wife and I did after getting our 1st 5'erwas to take it to a large parking lot without the parking bumps (key, no parking bumps) and practice driving, turning, braking, backing up. BOTH of you NEED to know how to pull your rig, If one of you is unable to pull the other HAS to, my wife can pull just as well as me, she's adequate at backing but all she needs to do is get us there, if it comes down to it, somebody else can back it for her, not saying she can't but it takes a while. Learn what your turn radius is. You don't want to be running over any curbs. Run through the gamut. If the lot is big enough get it up to 40 or 50mph and practice some emergency stops so you know what it'll do in a real situation. Adjust your brake controller to stop the trailer and not the truck as that's what your truck brakes are for and that could potentially cause problems with control. Practice backing up a lot, both left side and blind side (some parks you have to blind side back in. We spent the most time at that. EVERY trailer backs up different. They all have a different "cutting point" to them (when they start turning with respect to the truck. Learn it. That will make getting into back-in sites soooooo much easier. I've driven big trucks before and pulled big trailers, little trailers, and sizes in between. They all act a little different. After your practice session(s) take it out on some less traveled but larger roads so you can get a feel for it at speed. A 5th wheel when setup right (level and with a good hitch and brake controller) is VERY easy to pull on the highway.
I guess the gist of this is practice, practice, practice. Don’t be afraid of it but respect it.
Also a couple of things people tend to neglect. Lug nut torque, tire pressure (truck and trailer and spares too), and pin box and hitch bolt torque. Check them before EVERY trip. Don’t neglect your truck either. Engine oil, transmission, coolant, differential, and brake fluids, air cleaner, the list goes on…………………….
Congrats on your new rig! If you need any help, suggestions, or have any to offer, THIS is THE place. We’re relatively small here but there are a LOT of REALLY GREAT folks especially Mike the owner of the site.
Remember, there are no dumb questions. All you have to do is ask. Someone here should be able to help.
Cheers!!
