you probably already know this but if you're carrying that tank in your rig for off road use and tire fill up , try to get an aluminum tank . I carried an old steel tank around , and my whole kit (tank , regulator , lines , gauges etc. ) was probably 80 pounds. Then I got an aluminum one , muuuch lighter .
Also , make sure you secure and strap the heck out of it if it's riding inside the cab with you ....
