Hello all; I have been told that there is a lifetime warranty on the kitchen faucet. I just cannot find who makes it. Is it a Moen? How do I go about getting a replacement. How do I find a manufacturing code? Any help out there?

Curious! Who told you it was warrantied?
On my '13 the faucet lasted about 2 months, I replaced it with one of muh better quality from the clearance rack at Lowes with reimbursement from RW, but I don't think since Keystone took control that that's possible anymore.
Not sure of the faucet brand on yours, but if it is the same quality as my OEM I wouldn't want the same one as a replacement, warrantied or otherwise.

I will warn you that if you have the dishwasher changing the faucet is a royal PITA.
Sorry for the double post!

The gentleman in the plumbing section at a couple of different Lowes told me they had a lifetime warranty. They have been known to stretch the truth sometimes.

Our coach came with the pull-out single handle faucet and was made by Dura of Camas WA. The pull out hose developed a leak so I called them up. They sent me a brand new pull out hose and spray head no questions asked and free of charge. This was about three years ago.

Yes, it's true! Our Redwood neighbour here at the RV park contacted them after the kitchen faucet handle got stiff to move, they sent a repair kit that cured the problem, free of charge!

Dura. Absolutely has a lifetime warranty. Have received replacement valve kits free of charge. 2014 38GK.

The pull out spray head on our Dura kitchen faucet would not return back to stream after using spray. Removed it and soaked in a plastic bag with either CLR or Lime Away and it was very little help. Emailed Dura and they requested several pictures showing the model type of faucet and one showing their name on it. Several days later a new spray head arrived free in the mail. Great customer service by Dura!! We did change the guts of the valve assembly with Delta type parts as they were identical and stopped the occasional drip by the valve handle on the countertop.

The lifetime warranty is nice but I still ripped ours out and replaced with a high end Moen. Now it feel like home. Have not done the vanity yet as it is still working fine.
I did the same with the ceiling fan and installed a much nicer unit.

Our Redwood was Dura-Faucet. They replaced the bathroom shower fixtures without question when the "nickel" finish would peel off to reveal the chrome behind it, but after 2 replacements for the same thing I decided I probably wasn't going to win this game.

Not an RV owner yet as we are still in the research stage however we do have experience with lifetime warrantied faucets. The builder who built our home installed Delta plumbing fixtures. Making a visit to our local Lowe's to get a washer for our kitchen faucet when it started to drip. The Lowe's rep in the plumbing department told us that Delta has a lifetime warranty and directed us to where we could find their contact information. After calling Delta, we had the part we needed within a week. Good to know though that this is also true for the plumbing fixtures in RVs.
