The Frontier boxes are good quality, but for my money I prefer to have my boxes custom made to fit the frame/boat set up that I am actually using. My front drybox, e.g., is 44 wide, to exactly fit the inside diameter of the boat, and thereby serve as a replacement for the thwart/crosstube, helping keep the sides of the raft apart. It is also built only 15" tall, about inch less than standard pre-built off the shelf-boxes, which means the profile across the top of my boat is lower, flatter, etc., making for nice surfaces to lay on, sleep on, walk across, etc. My captains boxes, likewise, are the precise dimensions I wanted, and same height as the main drybox, making everything more or less uniform. I like the frontier captain's boxes I had but-for two things: Hinges are bolted on, and thought stainless and all that, sort of rough and tumble compared to a nicely riveted or welded piano hinge and, like another poster said, the latches are somewhat oversized, and also bolted on, not riveted. Rivets and welds make for a smoother profile. Paid more for the custom boxes, but since I boat often and long, figured I'd get exactly what I want instead of an off-the-shelf product. But, otherwise, the Frontier boxes are just as good. Oh, forgot to mention waterproofness - - here's my 2 cents on that - - if you plan to flip and flip often, and are really worried, than worry all you want. I run a dory most of the time, which takes on some water throught the hatches, but a sponge takes care of it. Kayakers sponge out their boats, etc. I think being "waterproof" and all that is oversold. My boxes will leak in a flip or a wrap, but otherwise, they don't take on any water during constant use on most rivers, big and small.
