I have a supply tube that needs to be welded back on to my existing tank on my SII, 345/727. Quotes are coming in at about $90-$125. I might as well get a new tank and sender and be done with it. But should I go with the 33gal steel or 19gal plastic? I'm going on a long trip this summer from Phoenix, AZ to Northern CA. I'll be pulling a pop-up camper as well. I'm thinking that maybe I should get the 33 so that I'll only have fill up about 30 times instead of 50 What have you guys done and how has it worked out for you? Will I need to modify my hitch if I go with the 33gal. I have a 2' spring lift. Back Country Binder's has the 33 with attached skid plate and sender for a decent price, it seems? Appreciate your thoughts on the pros and cons.
