I carry 2 5 gal cans on top. They are the military "Jerry" style. I have the screw, airtight seals on them and carry horizontally. Up top I have 2 Thule bars with a 2X4 cradle for them. They are secured with 3 ratcheting tie downs which seem to do fine going down washboard at 40mph in Death valley. I am going to make a welded steel carrier for the roof for the cans, but would really like a rear mounted bumper option. As for putting them on the hitch post, that's fine if you are not going to be offroading. The departure would smash them up.

Good luck.
