If you are planning to feed a shower with the overhead tank, your press will be very little. Have you ever used a camp shower (a plastic water bag you hang from a tree) ? You can get wet and it is better than no shower but not much press. Are you going to need 95 gal? Are you going to heat water. You might think about removing the drop axle and put a tank under the truck. Just a thought. Good luck Kenn
