Lots of folks on this site will try to talk you out of an aux tank. I feel my RDS was one of the best mods I have done on the truck. Having extra fuel capacity doesn't mean you can't stop when you want to. But it does give you the ability to choose where you stop. With 96 gallon capacity, I never have to stop for fuel during our typical weekend trips. On longer trips we can stop at rest stops to use the restroom, walk the dogs, take a break from driving. Much nicer to do that than be forced to stop at a truck stop.
This.
Like Bionic Man says, it is much more enjoyable to stop at a rest area for restroom, walk the four legged kid(s), and take a break from driving, I have to stop just once a day for fuel now.
