+1 for Frontier Play dry boxes
I bought 7 frontier play boxes about 8-9 years ago. They have done well. One bent hinge, some rust on the stainless hinges and a broken seal from the backside of a bolt that should have been located in a different position, but all the rest of the seals are still in good shape and are still glued in place from the factory. At least one large box did not seal too good when a friend flipped his boat in house rock and a few gallons of water managed to get in when the boat was upside down for an hour. I am not sure if I have ever seen a boat flip and not have water in a "dry box". I might test the rest of them in my hot tub, kinda curious and getting ready for a grand trip. A couple of the boxes have taken some "hits" that probably would have cracked the american made boxes I have used before. The FP boxes have a slightly more malleable aluminum, so rather than crack, they bend. They are a bit lighter than american made boxes, but seem to hold up well. Mine are true to size, just about a 1/8" less than advertised, so they fit in the bays well. I bought the matching black ethafoam for both top and bottom and recommend the foam as well.
