Oh, so you do have the 33 gallon tank? That’s good to know then. That helps!I have not towed far enough to need the larger tank but I love having it in general. 900+ mile range... I think almost everyone on the site has been glad they got the 33 gallon tank.
The tank itself doesn't weigh that much more than a smaller one so you could always out less fuel in it since the payload hit includes a full tank. You'd get 7# back for every gallon you leave out. You'd have to decide if 70# is worth filling to 23 gallons.
The range really is incredible.
