I use Stanadyne Performance Formula. Stanadyne is a fuel injection equipment manufacturer. It's diesel fuel additive is approved by Ford for the Powerstroke, GM for the Duramax, John Deere, VW (Bosch VE pump) and other diesel manufacturers. Cummins has not approved it, but does approve others.

Lubricity is the big issue with diesel fuel. The new ULSD is very close to the low end of the recommended lubricity scale. You can find lots of info on this on the internet. Injector pumps need lubricity if they are going to last like they should. New injector pumps are expensive. A good additive adds lubricity to the fuel. There are only a couple additives out there that do it and Stanadyne is one of them. There are also lots of snake oils out there too. Do your homework before deciding on a fuel additive.

In our part of the country additives in Diesel Fuel are necessary. Diesel fuel will gel up below 20 and it must be treated with 40% #1 or anti-gel additive. Many times #1 is not available or to expensive to acquire. Most of the trucks here have fuel heaters in the tanks or lines to stop gelling. I have not seen any motor homes with fuel heaters. If a customer fills his coach in October, before dealers winterize their fuel, he better well add anti-gel additive in such quantity to stop gelling if he wants to go south in the winter.

Seth, additives have little to do with water in fuel you purchase. That's why all diesel engines have a fuel/water separator. Specifically, you are cautioned (by every diesel engine manufacturer) against using any additive that causes water to be adsorbed to the fuel, allowing it to pass through the fuel/water separator further into the fuel delivery system.
If anyone wishes to use a specifically designated diesel fuel additive, or in your case an anti-gel additive, it can only help. A neglectful thing to do is allow the RV to sit for extended periods with a partial tank of fuel. The air space allows moisture in air to condense into the fuel,(diesel fuel has a natural affinity to attract moisture) settle to the bottom, which allows/promotes the growth of algae. These links explain better than I.
