A good friend gifted me the 3.3 gallon waterport. While I was trying to put it in a place which had easier accessability than inside the rail, I figured out how to 'hinge' down one of my Victory 4x4 side rack supports and turned it into an overland "shelf." This has worked out great, and I even use it for a small step when I pack up the RTT. Looking to do the same on the other side. I'm just not the kind to roll around with an axe or shovel, so this worked out well for my application. It doesn't sit out far at all, and the 3.3 fits nicely along the truck bed.
