My '77 Excella 50 had a smooth vinyl wide stripe. Maybe the PO had theirs fade out or crack so they removed it and used paint.

Our 79 Excella 500 had a blue plastic stripe and it wasn't bumpy like yours, it was smooth. It had two light blue stripes on the solid blue that ran all the way around about an inch from the top and the bottom. They were one very thin line and one a little bigger that ran parallel to each other.
I have a 78 Argosy with the wide brown stripe around the middle. I sanded and repainted that stripe five times and still got the ripple effect. I know this Argosy can be painted because I have painted almost all the exterior myself. It's just the stripe that turned out, shall we say, not smooth. Used good wax and the Cyclo to make it look as good as it possibly can. Not too bad now and I am probably the only one who notices it. Not much help for your problem is it? The stripe did look better with the new vinyl insert outlining it.
My guess it that it has been painted. One clue is the paint on the rub rails that surround the blue band.
My 78 Excella has a blue band that is vinyl clad aluminum. When I stripped the exterior, I got stripper on the vinyl clad. (dumb thing to do). The stripper stripped some of the clearcoat off the vinyl and left a... well... mess. I ended up painting. But first I gently sanded to even out the mess and then painted with Rustoleum undercoat, sanded, painted with Rustoleum Royal Blue which is a perfect match. Here are some photos of the process and the result.
If you choose this route, remove the Excella 500 logo before starting the work. While it is off, polish it and put it back on once the painting is done. The last picture shows some of the dimpling caused by my attempt to clean off the clearcoat which I aborted when I realized I was creating a bigger problem. The gentle sanding helped to smooth out the dimpling and over time, it has improved. I painted the belt in 2002 and it still looks good.
Many thanks for the answers. I did some poking around in the corners, and it's definitely painted. I don't see any evidence that there's another layer under it. Oh, boy, I'm coming up with SO MANY ways to spend my poor tax return.
This trailer spent ten years in the desert in Arizona and then six years in a barn in Michigan, and now it's had a year in soggy southeast Georgia.
Resolved, I am, to strip the stripe and repaint it. Wonder how it would look in hunter green? Wonder if I can find the inserts in green?
