I believe they are truly equal as far as pecking order is concerned. The differences are going to be trim colors, and small things of the like. They are basically the same thing except FR puts a different label on them so two dealers in the same area can both sell them. More visibility : when I was looking at RV's, my goal was to look at as many different brands as possible to get a good idea of differences in build quality, etc. If there were two dealers in Columbia, SC, one with Sierra and one with Sandpiper, I would've basically been giving FR twice the amount of looks without realizing it. Only problem is, most manufacturers do this, so its not like FR has any advantage.
