My experience has been this:
A single stage paint won't wear as well as a catalyzed paint...often by a long shot and if you're building a truck that will be used as a pickup, you need tough paint.
A catalyzed paint almost can't be had in a matte finish. Some companies claim they make it, but it all looks very glossy to me.
If you use a gloss finish in the interior of an AD truck, you may not like it. I figure that's why GM never used it. But there again, a few people think it is ok.
If you want a matte finish for the interior, but you want a catalyzed paint (for durability), then do this: paint the catalyzed layer first and then go over it with a matte finish clear coat.
As for color, that's a personal thing.
There is a PPG paint (MAE Omni) that comes very close to the original interior color. It is Brand Code: 4067, OEM Code: 63, M6253A, 8ZFEWHA, Description: Light Sandalwood. This was originally a Ford exterior color. Has less "gold" than some attempts at the original color I've seen and none of the green some seem to have. Have them add a de-glosser. 4 parts paint, 1 part reducer. It dries quickly and sprays nicely.
