Have been using these for many years

Ditto on Diesel Kleen.

On a previous sticks and staples brand new class A I owned I used Diesel Kleen from day 1. Five years later I rebuilt my Aqua Hot and there was no soot and just a thin yellow coating on the burner and nozzle.

Never add fuel without it.

I have mostly never used it. The only times that I have is when I drove from S. to N. in a short period of time and was concerned the Southern diesel at the pump did not have adequate additive that the N. fuels have. I full time so the RV is driven year round. If I was parking the RV for an extended period I would likely add an additive.
