Got my 1st 5th wheel toy hauler back about 15 months ago.
I installed air bags in our dodge 3500 DRW make the ride not so harsh and made the truck ride more level.
The thing I found out that the trailer takes a tad longer to respond to the input of the steering while backing up for me it dose.
Also it will track slightly inside of the truck so allow more room on turns.
I had a guy help me get into a spot once I kept trying and trying and he says just pull up more then you think you need to I was ok...
well it worked great got it in the spot the 1st try.
Just take it slow and have fun
