The front sticker by the Zamp Solar Input is the official tire size and inflation info. It's likely it has the official weight on there too.
In the back near the outside shower is all water, flush, etc stickers.
I found one video that showed these sticker really well. But they too were all faded away.
Then I found this video which goes all over the inside before going around the outside. Some of the outside shots show stickers. I made screen grabs of a couple. The stickers by the shower are visible. The ones at the front are not really but we all can see that yellow part of the front sticker to know it's an inflation chart and likely a weight chart as well.
Hope this helps.
A call to Winnebago Towable Customer Care (574) 825-8052 might be able to get them to send you a pdf of the sticker content. I don't know but it's worth a try.
