As an update, I checked what the case at the shop was and it turned out to be Valvoline muli-purpose red #2. I picked up some Valvoline full synthetic #2 (SynPower) and am greased everything on the truck. The truck DEFINITELY needed a greasing as it took quite a few pumps to get everything lubed properly (boots were very very empty). From what I've read on multiple other BITOG posts, the Valvoline full synthetic is hard to beat as an amazing "one gun for everything" grease. It isn't awful at ~$9/tube, especially since I won't go through it extremely fast only greasing my one truck (13 grease points - 11 ball and socket joints, 2 universal joints).
