Well, I'll tell you.
1. you can refuel when you want to, not when you have to.
2. In the case of a 3500/350 truck, it makes the truck ride so much better, at least mine does. (3500)
3. The cost per gallon may be as much as 50 cents per gallon difference from state to state. 80 gal or so makes a difference.
4. The convenience of all the above.
5. The difference in mileage is not a factor when pulling heavy. I'm at 28,400 gross, when close to empty on fuel don't see any difference.
As for the spare, can't speak for that, only for the aux tank. My 95 gal in bed tank is the best thing I ever did for traveling, who cares what the bladder (yours) holds, it's the fuel tank that counts. You can stop anywhere to control the bladder!
Bottom line as for as I am concerned, make sure your truck/trailer configuration will handle the tank/weight that you will be adding both GVW and GCGVW.
This is my opinion and mine only, yours may vary!
