We spent 8 hours last week (two 4-hour days) getting professionally trained on backing, parking and more safely towing our Airstream. We used our own equipment for the class, which was really great. We also trained as a couple, which helped radically improve our communications while parking and made it possible for both of us to either sit in the cab or direct from outside while parking, and in a pinch, to do it alone.
FYI, we've owned our Airstream for 2.5 years and have towed over 13K miles, but still learned a ton.
Best RV money we ever spent! We highly recommend this course, especially for folks who, like us, had never towed before owning an Airstream.
Our trainer was incredibly patient and helpful, and now we can back into pretty much anything - even blind-side or a curved parking spot.
Many of the key things we learned are completely counter-intuitive, and we would not have picked them up on our own. He also made us practice uncomfortable scenarios that we would not have attempted on our own, even if we found a big empty parking lot and set out some cones.
We contacted several CDL schools to locate one that offered an RV course. Here's where we got our lessons, and we're super-happy with the one we chose: http://cdstruckschool.com/
We found a list of CDL schools via our state's Department of Licensing (DOL) site: http://www.dol.wa.gov/driverslicense...edschools.html
so perhaps you can find the same initial reference point for your state, which would then help you find a CDL school near you that offers similar training.
(No, we're not affiliated in any way with this particular CDL school or the WA DOL. )
