I've been shopping the new GM 3500 SRW HD trucks and like others I'm surprised and disappointed that Adaptive Cruise is not an option for these trucks. I've had a Benz GL 450 with Adaptive Cruise and I don't want another vehicle without it, especially with all the interstate cruising I do pulling a fifth wheel. I've test driven the 2020 GMC 3500HD Denali, Chevy LTZ and 2019 Ford F350 Platinum and the GM trucks have a lot to like with the trailer tech to match the Ford plus the 10 speed trans, heads up display, auto 4WD, camera mirror and the payload capacity I need (335# more than F350). Unfortunately I can't see buying a $78-80000 truck without the Adaptive Cruise so I'll just have to wait till GM includes it. With the forward braking and distance indicator already included it's going to be added. They pulled the same dumb GM stuff with the 1500, not including it in 2019 but adding it for 2020. It's hard to believe Ford has had this on their HD trucks since '17 and GM still leaves it off a 2020 model.
