One thing GMC did across the board was to paint the dash bezel and glove box the color of the interior. I'm thinking,although Sierra Grandes started before Cheyenne Supers,they didn't get the woodgrain dash until '71. I'm wondering if only 71/72s say the trim level in the fender badge. Across the board,a Custom got the same thing as a Chevy Custom...mid-level until Sierra Grande came out,when Super Custom became mid-level. I know in 71/72 Super Custom was equivalent to Custom Deluxe. I assume in '70 Super Custom was equivalent to a Chevy Custom...once the Sierra Grande came out.
To make things confusing,GMC called their 133" Wideside a Custom Camper,not Longhorn. You could have the Custom Camper pkg option on any 2500 or 3500. So,a 133" Custom Camper could be a Custom Camper Custom Camper with any trim level. I have fender badges that are 3500 Custom Camper. I have no idea what they would have come on. I have seen 127" 2500 Custom Campers that had the door script and 133" 2500 with the door script.
