Hey guys. I’m in the process of finding the cash for an edc. I want to run the kp 6.5 gallon tanks under the bed behind the axle. How many can i fit back there? 2,3,4? It will just be tanks no valves or anything else. And I do have a byc watts behind my axle also. I would like 4 but not sure if it can be done. Thanks for any help. Pics would be sweet.
