I have a 25 gallon tank burning appx 8 MPG, my half tank would bring me to 96 miles. If I go long distance I plan ahead using the link I provided eariier.
For sake of dicussion I am going to Florida this summer, I have the route planned and what cities/off ramps I will take, maybe thats a bit obsessive but I try to leave some comfortable range in the tank between fill ups. I wish I had the range as some of the other trucks do. This is my first TT so the next truck will have more capacity, believe me.
Not a bad policy to go 1/2 tank as I believe we all need to get out and walk a bit.
