I would also like more info on your water system. How many gallons does those two tanks get you two? I was debating on putting a tank right down the middle but don't want to give up ground clearance. My other option was I could mount the tank inside the main compartment. The largest tank I could fit and still slide in my gear storage box and ice chest is 11 gallons. I was leaning to that but if your set up is more then 11 gallons I might rip off your set up lol.
