My 5er has 5 tanks, 2 black and 3 grey. The blacks are 52gal each and the way I figure it, if my family can fill 100+gal of black in a week, or even two weeks if we ever stayed somewhere that long, we got some issues. Lol! In shopping for a portable tank I had already decided I was NOT using it for black water, grey only. If I had to empty a black tank the whole rig was going to the dump station. My largest grey tank is 54gal. Doing some math if I were to get a portable that could do a grey tank in one haul, that's gonna be over 400#. I'm not hauling a portable behind a 3500 DRW diesel truck. Talk about ridiculous looking. Lol! Besides, I can use some excersize walking it to the dump station. Either way I have to make 2 trips. So I ended up getting a blue Barker 25gal with air filled tires. Much quieter rolling thru the campground compared to the plastic wheeled ones and it rolls pretty easy too. Going the next gal size larger the tank gets wider and longer, so that starts to become an issue for storing it and travelling with it. The 25gal fits perfect in the truck bed between my hitch and the front of the bed and light enough for one person to pick it up to load it in the truck bed too. Another big selling point for me was it's made in the USA, and right here in Michigan. Win, win!
