I recently used a piece of plywood, 2x4's and ratchet straps to haul 2 jerry cans to a weekend near Gunnison. Laid it across the factory rack rails. Strapped it down. Worked great. I want a real one, sure, but this was the quick cheap temp solution.
Or just bring Perry on your Maze trip and have him haul it all - that's my preferred method! BTW, you know we did the Maze 2 years ago on the Outlaws Run. Great area. I think there is a Trip Report here.
