I bought a RDS 70 gal. tank when I bought my 2012 Ford F250. Towing I can fill up in N. Cen. Fla drive to Slidel, LA drive to San Antonio, TX drive to El Paso, TX drive to Tuson,AZ and still have a lot of fuel left. Reverse on the trip back unless I go another route. Here locally when not towing I keep the tank full and fill it about once a month at a Wally World where diesel is the least exspensive. I plumbed it through a SW elec fuel pump and can use that or gravity, mostly gravity. It weighs about 480lbs but that doesn't seem to be a problem. So, I carry 96gal and can pick and choose where I want to buy diesel.. I can't say enough 'Good' about RDS.
