Before buying the 5er, the most I had ever towed was a 16' utility trailer with a tractor on it. Pulling out of the RV dealer lot, my first thought was "wow, that thing is huge". But after towing it 100 miles home, and "only" jumping one curb, I realized it was actually very easy. Did make me especially aware of the need for wide turns. After a practice session in the high school football stadium parking lot with some cheap orange cones from Walmart practicing backing, I felt comfortable in hitting the road.
Enjoy.
