I dont feel it will be too hard, and i agree with MSD, rural areas are easier to find it and if you have the right tools you can find it way cheaper then "truck stops" just by going further away from them. ex i had a class A diesel pusher last year, and truckstops right off the interstate where and easy 50-90 cents higher then if i was to find the little gas station down the street, problem was my 38ft class A couldnt fit at the smaller ones so I had to go to the truck stops.
IMO it's not worth it but I'm more utilitarian and don't require massive torque on demand. My max tow has a higher payload and tow capacity than the diesel and the only time I've found it lacking was with 6k behind me going up a steady 8% grade. My gas engine has been fine so far and it'll only get better when Eaton finally drops the TrueTrac and I re-gear. Adding in the overheating and pulling power issue the diesel had (dunno if resolved), I have zero regrets going with the 3.6L.
I guess what I'm saying is that don't buy a diesel because you want to do typical diesel things, buy the diesel because you want the torque driving around and don't care that you're spending more.
