You sir, are a gentlemen and a scholar. I thank you
My next thought is that my shanks are too long. I picked up everything in that picture for a whopping $300, so I was more in the "shut up and take my money" mindset than anything haha.
I believe I used 3 1/4" SS shanks for mine. You really don't want them to be too long because you also have the end barb to install and the hose sticks out past that a bit. They will get in the way of the kegs when trying to get them in/out. Too long and you might have a hell of a time. Mine already feel like they're right to that point of being too much in the way.
i didn't pay much for mine only because I scored on most of the materials used to build it. But I love mine. It goes on vacation with us, it goes camping when we have a large group and to friend's parties all the time. I bring it to family get togethers--we have one in 2 weeks and it'll be filled with some hard lemonade I made for a buddies wedding that I want to get rid of.
I use the thing so much during the summer times, and everyone who sees it is obsessed.
It is a bit too much when we go to the river or over to dinner where there aren't a lot of people, so I made the mini one (posted previously) that does up to 2 gallons. That thing is awesome because it's enough for myself and a few people plus it's super light and small. I bring it to softball games, the river/lake...etc.
Mine keeps cold with a bag or two of ice for many days. I do suggest trying to find a method of recycling ice. I use small water bottles, blue packs and I've made a few ice packs utilizing the food saver. This keeps moisture down inside the keg and is cheaper than buying ice.
So the moral of the story is you will use the crap out of that thing if you get out a lot. It's a great tailgating thing too. You can even bring it with you when the lady tries to take you shoe shopping. Just plop a camping chair outside the car and enjoy your day... Haha
