I can see just fine with regular mirrors and its what i prefer. On my Ram they are on the side unless you turn the mirrors up of which i dont have a need or want. I just cant find em or even know where to look.
I pulled my 35ft King of the Road with a 97 Ford PSD and going up 50 towards Lake Tahoe i never went under 55. A CHP kept pulling along side me in the passing lanes and then drop back when it went to single lane. He finally stopped me and when he came up to the truck told me i had done nothing wrong, he just wanted to know about the truck as he was in the market for a new one and couldnt believe i could maintain the speed limit. That truck had a chip added.
My 2011 GMC that i just traded off had one NOX sensor replaced at 70 some odd thousand mi. It had the def tank replaced at 600 mi because of poor ex fluid message and replaced again at 79k mi because of check engine light. It had many different brands of def in its life with me.
