My dads 2003 c1500 Silverado has a curious problem.
The PRND21 display is super dim. To the point that on a sunny day you dont know what gear you are in.
All the other displays are as bright as they should be
Anyone else had this problem and know whats going on?

The vacuum fluorescent display is going bad. It happens. You can replace the cluster or replace the VFD. Replacing the VFD can be a PITA if you don’t have desoldering tools. You could also replace it with a late model cluster that has LEDs instead of the VFD.

I would try the repair myself before sending it.
The repair is VERY easy, and takes little time (probably less than you'll spend boxing it and shipping it).
If you have any experience at all with a soldering iron, you can do this. Mine had the issue, and the repair procedure solved it.
The issue is that [edit] the solder on [end edit] several SMD (surface mounted device) resistors in the cluster crack, making the display dim. You simply open up the cluster, ant touch the soldering iron to the ends of these SMD resistors. The solder reflows, and the crack disappears. If you want a little added margin, you add a very small amount of solder to the joints.
Here's a short concise video showing the repair:
