This is an extremely common probelm with the optional 32 gallon tank at those exact fuel levels you stated. Please contact Ram and complain. I did and they said "They have not recieved enough complaints on the issue to do anything about it."
Yet many have complained on here about it.
Hopefully, the squeaky wheel will get the grease.
