Glad everyone is OK! Its a good reality check for all of us!
I've heard of several people hitting the ditch and saying they should have been in 4wd. Just curious what most manufactures say is a safe (mechanical) speed to run in 4wd? I have a 2500 Duramax and I belief the manual says 50 mph (not positive).
If the roads are slick I'm in 4wd Up to around 65 . If I hit a dry section I go back into 2wd . Hubs stay locked in all winter .
