First, make sure you are comparing carry capcity apples to apples. CCC, OCC are different, and the format of Tiffin's sticker in the closet has changed over the years.
Most 32SAs are on the 24k chassis as well. The 32SA on the 22k chassis is going to be a bit low on the carry capcity; the 24k chaissis nets you ~1,500#s of carry capacity as the chassis itself weighs ~500#s more than the 22k chassis.
My "old style" Tiffin weight sticker as found in the back wall closet can be found in post 6 of this thread, along with more thoughts / details (and examples of the newer Tiffin weight stickers) within the thread.
