Small tanks are definitely a pain. I had a Chevy Duramax with a 26 gallon tank. You never want to run out, especially with a diesel, so it was less than 20 gallons usable. On long trips, where you didn't know where fuel stations would be, we ended up getting fuel about every 150 miles! VERY slow progress.
We always kept 2 plastic Jerry cans in the back for backup, not fun (diesel on your hands is very stinky stuff).
I thought the solution would be to add an auxiliary tank, or maybe replace the stock tank with a larger one. Both options were available. BUT, just one problem. The pickup was a 2500 (3/4 ton) and the fiver already had it maxed out for weight. A small increase in fuel tank wasn't worth the cost and a large one would put the truck over weight.
Not an easy fix.
Diesel is only 7.1 lbs/gal, so a 20 gal aux tank, full, should only weigh in about 160-170 lbs, max. Extra 200 miles, or 3 hours for a fairly small weight penalty.
