I know the thread was started over a week ago so not sure if you managed to select the tools you need yet. Many of the sizes for the 1/2 ton Chevy/GMCs are the same starting in '99/'00.
The main ones to have are:
*1/2" Drive Sockets:
-22mm[7/8"] - lug nuts (if still original), tie rods, lower ball joints.
-36mm[1 7/16"] - axle nuts
-18mm- brake caliper bracket bolts, upper ball joints, misc others.
-15mm - wheel hub bolts, misc engine, frame, skid plate and suspension hardware.
-T55 Torx - some calipers are mounted to the bracket with these fasteners.
*Note that if parts have been replaced such as balljoints, etc., the aftermarket nuts/bolts might be larger/smaller than factory. As an example, most lower ball joint nuts for the 1/2 tons are 22mm but some replacement nuts are 24mm.
For 3/8" drive sockets, you'll likely need 8,10,13,15,16,18,19mm depending what you touch under the hood and elsewhere (12+14mm are also common replacement sizes), so just buy a kit. Not enough weight savings to justify only carrying certain sizes.
Wrenches are also best to have a complete metric set. You never know what you need. Basically 8mm thru 24mm, skipping a 23mm since it's super rare. (And yes, 11mm is a must for ujoint strap bolts, lol)
There won't be any Allen (hex) sizes as far as I recall and if there are, a regular set of keys will do. So don't worry about buying Allen sockets.
Use your space requirements and best judgement on ratchets. I recommend 1 good sized (24+ inch) 1/2" breaker bar and 1 ratchet for each drive size you carry, but different lengths can be useful if not completely necessary.
Hope this is useful and not just overwhelming.
You gotta have some ASE certs. LOL
