On our last trip out in October last year, the pantry suffered a failure. The pantry is huge, and it has 4 shelves that you can adjust the heights. If you have a 195, 196, not sure about the 192, 193, you'll know what I mean. I keep 2 plastic bins on each shelf, that keeps thing from rolling around. I can put a bunch of stuff on each shelf. So last year the plastic shelf holders broke. I have replaced them now with steel rails, that have steel adjustable clips. I am pretty sure this system won't fail. If you tend to fill up the pantry, you might want to replace the plastic strips with steel. 

Amazon has these. It requires four, 4 foot long sections.  I ordered 3 6 foot steel bars, with about 20 clips. I cut 3 bars 4 feet long, then used two 2 foot bars for the fourth. I had to add a spacer on one side cause these bars are thinner. I bought some 3/8 strapping and mounted them to shim the opening a bit smaller.  Heres the part number for the rails
