I did mine with Carefree toppers and had to do some work. On the front slide I trimmed the bracket some to be sure it didn't hit the window glass, and trimmed the flange corner piece to get further away from the glass. This may not have been necessary as the bracket fit under the glass.
On the rear bracket I notched the trim of the fridge vent.
On the rear slide I put the brackets on the slide flange instead of below it.
Carefree has a long and short bracket and I used long on both slides.
