An important thing to consider with the Gen Right tanks is what suspension you are running. The Gen Right tank will not fit with AEV suspensions, or any other suspensions with modified track bar towers that are on the axle without major modifications. A couple of years ago we had to cut down a Gen Right tank and trim about 3-4" out of it and then re-weld the entire assembly to get the clearance for the track bar tower/travel. Just something to keep in mind.
If there is enough interest in the Long Ranger tanks (ARB), I'd be happy to put together a group order with them. We bring containers over from Australia monthly, and can save significantly on shipping cost vs. individual purchases. If anyone is interested in that, shoot me a PM and we can discuss further.
