check out how we did it. to be a bit more clear than the video... revel agm battery boxes will prevent you from doing this. it may be possible however it may not be as strong. call roam rig, get those batteries out from under your van!
So I am thinking that what has to happen that is different from a standard install is: 1. remove battery boxes and all the brackets holding the tanks/running boards 2. modify the middle brackets by adding a flat bar and install rivnuts in the right places to bolt the bar up 3. weld some eyes on, 2 on passenger side, 1 on driver side, to hold the tanks Is that it? Sounds doable. (I do not have a ladder on the side, and I have already removed the AGM batteries).
