That’s very possible. Be happy with it..
There are two ways to make Federal emissions.
One was 2008-2010 100% engine killing EGR. Remember the 6.4L, and the difference it made when deleted?
The other is the current SCR technology that takes advantage of DEF after treatment..which dramatically cuts back the need for harmful internal EGR. As the years have passed and SCR technology refining even more, more DEF and less EGR is the approach.
So, for an extra couple dollars of DEF, you’re saving your engine internals from harmful EGR processing and all of the burned contaminates floating in your oil..
So, every time you are adding DEF, you are actually saving your engine from EGR death.

I still get a regen about every 500 miles when towing whether I need it or not........ LOL

Not set it stone. Even with my 2020 I have exceeded 600 miles and am currently over 600 with a soot % of 10. Towing will extend the interval. I have auto regen turned off so it has not completed an active regen in the background.
My 2013 (the unicorn) I could go from Maryland to Colorado without a regen. (all towing).

According to a spreadsheet that I have kept since I got the dealer to activate my DPF gauge, I am right at 500 miles non-towing miles between regens. The gauge is always showing 99% at that point.
Towing mileage between regens averages about 400 miles.
I did go 680 miles 1 time, but I was in Yellowstone with low speed limits so the truck never got up enough speed to regen.
It is difficult to keep detailed notes on DEF usage, but I definitely use more DEF when towing. Makes sense: More fuel, more DEF needed.

That ended when the 2017s came out. I doubt they brought it back with the 2020s

That is not experience in my 2017, but of course the newer technology of the 2020 trucks is going to be different.
According to a spreadsheet that I have kept since I got the dealer to activate my DPF gauge, I am right at 500 miles non-towing miles between regens. The gauge is always showing 99% at that point.

No indication of a regen. I had to buy the Banks idash.

Yes my 2020 would not tell you , but with auto regen off then it will notify.
Banks idash will report it too.
Trick to exceeding the 500 miles is EGT 4. If I can keep that at or above 800F then it will passively regen faster than it produces soot.
in my 2013 unicorn it would regen about once a month and exceed the length routinely.
