So i set up a RDWC using uniseals thinking i could get away with it but i was wrong. After a couple of failures on the dry run and a couple of failures on tge silicone run i finally decided to go with bulkheads and man are they proud of them. I was able to find 2" for 6 bucks which is way better than the 30 bucks i was seeing primarily. Here's the link.
