Default Aux Tanks in Bed

Hello, fellow GMC'ers. Forum newbie here. Need advice from you who have experience with putting an Auxiliary Fuel Tank (or having one installed) in the pickup bed.
I have a 2018 GMC 3500 Diesel Dually (CC, LB). Planning to go to Alaska this summer. My 36 gallon tank seems a little light considering the 10 MPG I'm getting pulling the 5th Wheel here on I-10 (flat land). I'm looking to add 30-40 gallons of diesel to hopefully double my range, while keeping the weight added manageable.
Are gravity feeders a big No-No? Are the automatic, computer controlled pressurized versions required? Worth the money? I am interested in hearing any and all experiences. Thanks in advance.
