I have a 1978 GMC Sierra Classic Camper Special C35. It was my grandpas from 1978 until he passed away a few years ago and was passed on to my cousin and myself. We've been trying to continually fix it up and keep it in good condition. Original canopy rotted off and we had to remove it, line-x the bed and put a new canopy on it for now.
I'm hoping to learn from the forums, tips and tricks for keeping this truck running as long as possible and in as good a shape as possible. Only 170k miles on it so far.
