I'm sure that Winnebago used the same faucets in a lot of models. The lavatory faucet pictured below is found in my Via. Last year it was starting to leak around the handle and this year it would drip all the time from the handle area. I removed the cartridge and found it to be a KEROX which I had never heard of but Googling it I found out is is a respectable brand with a growing market share, made in Hungary. First I found a Chinese knockoff on Amazon for a little over $50 and about 10 days out. Then I found a company in S.C. called Factory Direct Supply Company and they had the original KEROX for $14 and $8 shipping. I ordered it and it took a week and arrived today very carefully packaged! Works perfectly. In my research I found several other brands that said "compatible" but if the original lasted over a decade I figured I would replace it with the same. Anyway I'll post a few pics along with the info on the company. Hope this helps someone looking for a cartridge!
