Well…I went to Trekwood.com to search. I was surprised to see the YEARS option only go back to 2018…and my “door” search turned up nothing. So, I changed the years to 2023 just to test it and several “passage doors” of various sizes come up. If you are unfamiliar with Trekwood, they have a reputation for having high freight charges. Amazon has spoiled us all for delivery/freight, so go into your search expecting freight to be much more than you guess. Since they do not have backstock for your 2014 model, you will need to figure out how to paint the plastic veneer paper to match as best as you can.
I have the peeling paper veneer on all 3 interior doors in my rig. I just keep glueing the edges back down in a loosing battle. I have never taken my measurements to Home Depot to see if they have anything that might be cut to fit my needs, but I doubt they have anything appropriate thickness, and/or pre-cored for RV hardware. There is a “mobile home parts” store in Waco TX (about 1 hour north of me). I have been there and was impressed with all the stuff they have that might also work in an RV. A store like that might have “white/primed” doors that would come closer to fitting our units than anything at Home Depot.
