Some people believe that the rivets are better because they will fail before cracking the fiberglass whereas bolts will not and then excessive stress on the glass will break it. Replacing rivets is easy and cheap, repairing damaged fiberglass not so much.
With that said, Eveland's Inc does use a couple of bolts in high stress areas - no doubt because rivets have not served well in those few spots. My 2015 16 footer has two. Be sure you don't over tighten so much that you damage the fiberglass, and my preference would be to use flat washers as needed to spread the load over a wider area and I would also prefer to use Nylock nuts.
Acorn nuts, for appearance only, would then be optional.
Snap caps can still be used on the outside just as they are with rivets. Butyl on the bolt, and further waterproofing as needed.
