The swing-out brackets are specific to the JACKS, not the camper.
My B1500 has Atwood jacks, and the Atwood swing-out brackets fit perfectly. All I did was unbolt the jack from the mount on the camper, and install the swing-out bracket in between. It was hardly rocket science.
You may not have enough width even with the swing-out brackets, though.
The brackets I bought used off craigslist. Someone welded 2" extensions to them already, and my truck still only BARELY squeaks between the jacks.
There is <2" between the fender and the jack post, and my outer duals rub the jack feet.
