The one thing you should look at like one Bolter said is what are you going to used the truck for daily driver, show it, work truck etc.. If for work-daily driver you should consider a steel or S/S tank and if you decide on those two. For Shows, Racing etc. Poly or Aluminum. You also should consider a skid plate to protect the bottom of these tanks in case you should run over a foreign object on the road that could puncher your tank. Used Steel tanks can be boiled out and coated. New Steel tanks come Galvinised, S/S tanks are a little expensive but will last a life time. Aluminum tanks tend to have stress cracks after a while of steady driving on the roads and as for Poly tanks I would be afraid of it catching Fire or Rupturing in a accident. I for one believe in safety over the cost of losing a loved one. Be sides I do not have that long here on earth to break another one in! It has only taken me 36 years! LOL!
Just my though here fellow Bolters.
