We made the switch to a 5er 2 years ago. LOVE the way it tows, no more white knuckle towing and that help DW relax as well. Like said before, don't forget it's back there as I've caught myself exceeding the speed limit HARD CORE. It's easy to do when it tows like a dream.
Now for some useful info, Always before raising the landing gear to drive off on your trip, make sure your hitch is locked into place, only raise them like 2-3", get in vehicle and apply trailer brakes only and try to pull forward. This will make sure you're hooked together and latched, and if your not it should hopefully miss your side rails of the truck bed. If you raise all the way up and are not latched 100%, you'll soon know.
