I also have the 2 gal on mine, agreed the 3 gal should fit as well. I get a little less rattle with both pax on one side vs. one on each side as an FYI.
It seemed like I was power washing mud for hours the next day -a ton of silly fun though in the mud. Thanks for posting all the pix P. and for arranging this event! Nice turnout and great to see familiar and new faces as well.
