Disregard my last message... after I tried to post my last message I was finally able to complete registration and activation.
So i'm glad i'm not the only person who is having this 32gal issue.
I ran my truck down to no miles showing and the fuel arrow pegged and was only able to put in 27 gallons.
I figured they only put the 26 gallon tank in and the additional gallon was the line from the tank to the filler neck.
Maybe I'll try running the truck until it starves then see how much I can get into the tank
