So as for the new rear cap, color me stupid, but what are the advantages/disadvantages of molded/flat rear caps and BC new rear cap. Didn't see or find any info on it. Our current coach has a flat rear end which doesn't bother me.
Many people prefer the appearance of the molded cap over the flat rear. The new pseudo cap on the BC is a compromise. Probably costs quite a bit less while dressing up the appearance.
Some people think the molded cap provides better protection against water leaks. But with any type, caulking is required.
To me this discussion is a bit ironic. Over the past few years there there were frequent complaints along the lines that there needs to be more differentiation between Big Country and Bighorn. Now that Heartland has introduced some clear differentiation, there are complaints that they don't have the same features.
If the rear cap is that important, you can get a Bighorn. If price is more important, you can get a Big Country.
