A couple buddies and I are planning to build a mobile community brewery. I have searched to see if anyone has mounted their keggles horizontally to keep the height of a three tier system down. We'd need to have two burners per keggle. I have three kegs to convert for the hlt, mlt, and bk, looking at options for a small trailer. Been planning on a three tier system, but seriously considering a double tier with a single pump. Any thoughts or tips would be greatly appreciated.
