That looks like a nice trailer. Word of caution about pulling the decals off of the aluminum skin, take your time, don't use an eraser wheel on the aluminum and don't expect to be able to polish out the "stripe" left behind.
If it bugs you to see the shadow I'd think about a simple vinyl stripe in its place. Black or your favorite sled color or something.
I appreciate it. After getting the trailer, I realized that the stripes are painted on. It's an odd color and has some rust spots at the bottom of the door but after I remodeled and got the sleds in it, I think it'll work!
