Good to hear from ya'.

Interesting. Means maybe higher axle ratings = more money payloads. Sounds like GM is getting serious in the commercial LDT market. They have taken the back seat to the Ram and Ford SD for years now in that market. I know'22 GM 3500 drw move up to 10500 rawr has made a bit of "about time" comments from GM fans on those type of websites.
