How do you plan on mounting it? Does it stick down much further than the frame?
My tank like that is mounted by a pair of holes going through the middle of it. I've read that in time the welds around the pipes, going through, can crack in time. It's somewhat shallower than what yours appears to be.
If I might ask what roof rack are you running?Forgot to add that during the drive home it was very rainy and my wipers broke! The linkage seemed to have come apart. I parked under the shelter of a bunch of trees and used Two screwdrivers and a crescent wrench to take the dash apart and make the repair. I love the simple, utilitarian, field serviceable nature of these vehicles
