I think Eric’s Home Depot link should work for you, Fred.
Our coach didn’t have 20 years of wood exposure, like yours, when I made extra shelving a decade ago or so. Of course not even the shelf edging behind doors is exposed to light like, say, living/galley area cabinetry. But the Minwax Mike suggests worked great to make simple Home Depot pine look just like the surrounding cabinetry. We were at the Rock Creek Park in Twin Falls where I had no power tools and had to hand-make the shelves. I didn’t expect pine to stain match quite so well, and was amazed. Our cherry is “natural” I was told, finished but not stained; one Minwax application to the pine was all that was needed, aside from protective clearcoat.
