Not carriage bolts, but panhead allen head bolts crossed my mind. I wouldn't be able to get a wrench on both sides with a carriage bolt. I just used what I had on hand. I also wanted to use fender washers instead of flat washers.
I'm still in the fine tuning stage of everything, and will probably have different ideas when I actually put them to use. This is still very much a trial and error project at this point, but I sure have learned a lot. I'm sure I will make some tweaks still.
I'm already considering a top box....hmm..........
