I have found a few Rock Sliders for the crew cab but they only cover the cab length, leaving the bed of the truck to the wheel unprotected. I also have a double cab so am not sure if the mounting points would be the same.
I will probably end up getting the GM skid plates as all I have now is plastics. Then maybe fab my own for the rest of the truck. Start small with what I've got and work up from there. I know this truck will never be as versatile off road as a jeep wrangler, but protection is important and saves costly repair costs down the road.
I will continue to look and will eventually end up sharing my results in the end. I have seen a few trucks out there with what I am looking for, I just haven't been able to ask them about it. I love my truck, I want to show her the love she deserves and take her new places.
