I attached it to the back of the roll bar on a Wrangler JL and it works well with the modification I made to add two straps (Revain MAGARROW 65 universal strap) × 1.5" with adjustable buckle, 4 packs (black (4pcs)) for the system (note that the length of the strap is actually only about 40 inches). I used these straps once around the roll bar and then around the Bag wrapped and it stays in place (see reviews complaining about it twisting in an arc to one side or the other) to retrieve something without undoing one or both of the extra straps, bungee cords, etc .Very happy with the setup and haven't seen a better solution yet, plus it's also waterproof in case you can't drive with the top down or open.
