B20 okay

Just my experience in the past but I'd be careful with B20 Biodiesel, especially if you plan on leaving it sit in your fuel tank(s) for an extended period of time.

It has a very bad tendency to grow algae when it sits unused in a fuel tank and it's very expensive to remedy. Lets just say I found out the hard way and I did most of the mechanical work myself, new fuel (lift) pump, new fuel bowl, new injectors and new fuel level gauge and pickup in the fuel tank plus a lot of flushing the system and a lot of cussing too.

If you use the unit all the time, no issue but, if it sits alot , B20 can become a big and expensive issue. Even with regular ULSD, I run a biocide in every tankful, winter (when it's sitting idle) and summer, when I'm using it.

Little heads up...

From my Cummins book:

Use biodiesel fuel within six months of its manufacture date. Biodiesel has lower oxidation stability compared to petrodiesel. Avoid storing equipment with biodiesel blends in the fuel system for more than three months.

What does your chassis manual say?
