That tank you found 30” will not fit because of the 90 degree hinge that holds the deck in place and if you are wrong just buy a 1/8” that’s TOO BIG. I had my tank made which was if I can remember correctly 12 x 28 x 72 = 120 gal. I really did not want to spend the $650 I paid for it at first because I would never see it again. But now I am glad I spent the $$$ and glad I will ever see it again. As for the deck if it is not sagging in the middle and strong enough to hold 800- 1,000 lbs of weight just add one layer of glass and epoxy over the top all around to stiffen it up a little for the next 30 years or so. As far as how big a tank you need your motor / motors will tell you that I burn approx 1 gal per 2 miles better than that if it isn’t 3-5’ that day. Anyhow that gives me a range of approx 240 miles the question is how far are you going any one trip & how often do you want to fill up??
