Regarding bars... they cannot be snapped ON by hand. I'm pretty sure my husband uses the handy dandy tool to put them in place after there is at least some weight on the ball of the truck.
When unhitching - he raises the hitch to relieve some pressure from the truck/ball. Once "some" pressure is off, he gives the tow bars a quick jerk and off they come.
Unhooking the trailer from the Expy was basically the same except a pry bar was needed to get the bars off.
BTW - towing with the Expy was not scary. The vehicle pulled the trailer just fine and there was very little to no sway. The Expy was strong and didn't struggle at all. My fear with the Expy was the payload and the shorter wheel base.
I'm so discouraged by all of this, but trying to remember that we didn't have any troubles once we got to the site. It could have been worse! :-)
