"Auxillary" Fuel tank vs installing a new/larger tank

Hello - I have a 2017 Ram 2500 w/Cummins with the 6'4 bed, and just purchased our first fifth wheel. I'd like to add fuel capacity for towing and have seen a few threads here with some discussion...

We travel fewer daily miles now than in the past, but then it was common for us to travel 550-600 miles in a day. A 50 gallon tank would still have had us stopping to fuel up while towing. That's why we went with a smaller auxiliary tank. We carry about 70 gallons total which is perfect for us.

If you travel shorter distances, then a larger tank isn't as necessary.
