If you let it idle for extended periods without EB engaged it will elevate the rpm's.
I never know if or when mine is doing a re gen.
Yep, thats pretty much how mine is also but I have seen a couple MPG drop occasionally when driving that I associate with regin but that's the only evidence I've every noticed if that's even the cause. As for mileage, not to get in any argument here but I'd really be surprised if anyone even with 3.42 gears would get 20 mpg at 70 mph being the non aerodynamics of the front of the Rams, let alone getting that mpg with 4.10s. Not saying its impossible because nearly anything is possible but... The only way I get those mileage figures is when running 55 mph on a calm day, level road and I can push 21-22 mpg, but at 70, mine drops to around 16.5. I did do 25 mpg one day at 55 but I think I had a tail wind if that counts...Lol! All in all, I really like my setup with 4.10s, Aisin trans, B&W hitch and standard spring susp. Oh almost forgot, I have mpg getting bed cover too!
