RotoPax mounts on the back of my 07' Tacoma. RotoPax cans are somewhat new to the off road community and my experience with them has been nothing short of stellar. Seen here is the 4 gallon gas can, the dry storage rotopax container and the first aid container. I use the rotopax deluxe locking mounts to secure my contents. The "ECO" nozzle on the gas can takes a little getting used too but after a few times it's a breeze. I purchased all of the rotopax stuff here in the pics from Sierra Expeditions in Tempe, AZ but they are available locally at High Country 4x4.
