Thanks for trying that out. I typically run in m7 myself on my AFM truck to try to prevent lifter damage. I typically don’t run it in m8 unless I’m on the highway and the rpms are high. As soon as the warranty runs up, I will be disabling it all together.
Slightly off topic but I’ve yet to get an answer. On the older trucks, you could select manual mode and have it in the second highest gear (m5 or m7) and that disables AFM. Does that still work on the new style?
I agree on the 20” TB wheels. The stock AT4 20s look out of place with street treads but I’ve seen some with mud terrains swapped and they look good. I’d opt for 18s with duratracs myself though.
I really don’t consider them on the same level. The GMC is definitely more loaded.As it sits I’d go AT4 for the 6.2 availability. When the time comes Chevy gets the 6.2 trailboss or a higher end 6.2 styled trailboss (high desert anyone?) then it will be better. I really think the trailboss package is a rip-off. Awful expensive way to go for basically only a $1000 GM kit with some black OE wheels and duratrac tires. And then be constrained on everything else. Plus I hate the black front ends contrasting the body color. Only two colors that pull it off well is the black or dark blue.
