I would agree. Over that length, a 1/8" bow would probably not even be visible. I am sure mine has that, and there are no leaks. After putting a few hundred pounds into the bunks a few times while camping, I am sure they won't stay 100" straight, and 1/8" is not much, should easily be compensated for by the seals.
