I went from a 27' class A to a 40' diesel. Big difference in size. What I did was take my 'lesson', self taught, at 2AM driving around the Houston area. Not much traffic and I learned a lot. My lesson was a little over 2 hrs long. Swing wide at intersections, watch for idiots trying to squeeze between you and the curb at intersections when turning right, be aware of your tail swing, that area behind the back wheels will bang into stuff if you're not careful etc. Find a big lighted parking lot such as a closed Home Depot and practice backing and maneuvering where you won't hit anything if you make a mistake, and you will make a mistake. :) Enjoy the trip and enjoy the new coach. By the time you get home, you'll have plenty of left seat time to really be able to control the beast.....Dennis
