The outside corner trim used on a Travel Queen's interior is a cream colored plastic, likely vinyl, having a profile shaped like a Tee. The Tee has a barbed piece and a flat piece.
The flat piece has about an 1/8" wrap around angle edge, that covers just the corner and a small segment of the opposing 90 degree surface. The main width is only about 1" and covers the (usually) 1" wide board end made up of one or two 1/8" panels fastened to 3/4" framing. My trim was all damaged in one way or another: chipped, warped, discolored, etc. I pulled it all out and don't have a source for replacement material.
There are a number of outside corner replacement styles, but after working with the door frames and considering the inside corner beaded gimp, as well as additional trim pieces still to cleanup and install, all being in the eye-popping cream color, we decided we'd like to try and match the original style for the outside corner trim.
Many of my barb channels are still filled with cut off barb, which was the smoothest way to remove some of the damaged trim, if you remember a past post.
We also like to think outside the box. Rather than spend even more time tracking down exact replacement, or using expensive specialty stores for products that may work, I've chosen the following method.
Home vinyl siding in "Prairie Wheat".
Notice how well the colors match with the door frame trim in the foreground.
Here's how the original trim works on an edge.
And here's an out of focus other side. Just a little of the trim lips over this surface, but in this photo the barb is NOT sunk down into the groove so you have to use your imagination.
Here you see it's profile, placed near the portion of the house siding I'll use.
I'll rip strips on the table saw that uses the small wrap around bend of the siding, cutting the other surface to 1.25" width (to cover various panel chips and imperfections). As there is no barb, I won't have to re-route a groove, but instead I plan to fasten the trim with the black screws in decorative brass washers, as will be used in various other functions throughout the interior.
Each siding board has two 90 degree channels I can use, in twelve foot lengths, so I'll have way more than needed, but I got two boards just to have some extra and because it was in the clearance bin for $3.99 a piece.
I also picked up a U-channel (or J-channel) used to retain the ends of the siding for home installation, to try and adapt for the bathroom door opening edge. The intention there is to cover the exposed wood for wet-bath purposes.
