The 32YE Vista with the 4 door refrigerator (the major of them have 4 doors) have an odd shaped cabinet to the right of the fridge, too deep to make good use of all the space conveniently. Since our old Fleetwood Pace Arrow had a slide out pantry, that's what my better half wanted in this space to store cans of food, making it easy to get too.
So with a lot of planning, measuring, and engineering, I figured out how to install this pantry with blind sliders that need to be aligned. It works great, but I now know why Winnebago didn't build the 32YE with a pantry at the factory. Took me about a week of spare time to complete.
For those crafty fabricators out there, the right wall of the cabinet required a 3/4" plywood sheet screwed to the stud where the original shelf was originally attached. This 3/4" plywood acts as a strong anchor for the pantry weight. There's a stud at the the top of the wall to screw the plywood to also. You can find it with a stud finder.
In addition to the 3/4 plywood, it needed another 3/4X4X27" spacer for each slide rail. I used 2 slide rails on the right, and one on the bottom, all of them 24" long, triple rail. The slide rails are 1/2" thick, so with the right side wall spacers (3/4" plywood + 3/4" X 4 runners for slide rails), this puts the pantry almost exactly in the middle of the cabinet, assuming a 5.5" wide shelf.
I'll let you figure out the slider alignment tricks. Too much to type.
