"Thank you! Will that book give more info than a smart phone? Is there an app to find diesel on the road? "
You can get The Next Exit as a hard copy book or you can subscribe to get it online, in which case they give you a free app for your phone. They publish a new version every year.
I got the book because I like to have it open on the table when I am planning my next day's route and stops. Just seems easier to do then on the computer. I can see all the exits that are in the same area and I can flip back and forth from one state to another real easy. And I have it open in the truck so I can glance at it when I pull into a rest area. This is an extremely handy book to have. Just my .02
As regards your second question I use the gas buddy app (FREE !). You will find that many on this site will recommend it. Set it for gas or diesel and use it to find the cheapest price. You can preplan fuel stops clear across several states if you want to in order to find the cheapest fuel.
You really do not need to worry about finding diesel on the road. That's where all the semis are so there is diesel at most every interstate exit in the country. Just fill up whenever you have less then about a 75 mile range left in the tank (or whatever you are comfortable with). And if you're serious about traveling, you might consider installing either a larger fuel tank in place of the OEM tank or adding an auxiliary tank to the bed of a pickup, which is what I did. I now carry almost 80 gallons of fuel giving me a towing range of over 900 miles.
* I pull a 35' fiver (Big Horn 3010RE) that has a nice rounded nose and GVW of about 14,000 pounds. So far I average 11.5 - 12 mpg, but the truck (diesel) has less then 5000 miles on it so it still may improve a little.
