Best Towable Waste Water Tote for Beach Camping

Poop cannon to tank in the back of the sub. BTDT I have 40ft or 1 1/2 waste water hose to see the contents. The only difficult part is evacuating the full hose off the poop cannon. You are at a foot off the ground with 40 feet of sludge or gray angled up to the rear of the sub/truck. You take off the hose from cannon and raise immediately over your head. Walk the contents in the hose back to the sub/truck.
