Here is my single ARB in the area you are questioning. I run the single as I only need it for my rear locker the front is a e-locker for now. I use my SB compressor for airing up i transfer it between vehicles
Yea for me its saltwater, I carry 2 12FT poles, fishing cart, bucket, bait cooler and gear bag, chair plus bag for food and snacks at min. Sometimes I bring a weather pod bbq grill and small folding table.
