Oh yeah. No problem.
It has a soft seal between the lid and base. The latches are SS (assumed), but I can see that they might
wear to the point where they don't stay latched all of the time. We had a loop strap going over it that helped hold it in place, but it really didn't contribute to holding the lid tight. It stayed dry for us. Tappan Falls is a pretty good test for dryness, I'd say.
We brought our cheap Coleman 120 qt cooler (w/ a few mods) as our main cooler and wound up sticking the frozen margs & marinated chicken in the Engle for a couple of days due to space limitations. Your not
going to have ice after 16 days on a summer GC trip with this cooler.
.....but, it didn't cost $500 either.
BTW, it is the 30 qt cooler I'm referring to. 19'' x 14''h x 12'' w
