The SW top lets you mount a roof rack and mount fuel cans to that. It’s not ideal but it’s better than trying to find space for a can when you have almost no room at all, or not having the can.The hard top has a bigger tank?
I would definitely be getting out on the boonies. But fuel would probably be an issue for me in daily driving. There are stretches of eastern Montana where you can go 150 miles between gas stations.
