I recently purchased a 2004 GMC Z71 crew cab. All is working well. I am approaching 115000 miles on it. Not sure what if any mAint has been done to it other than the obvious engine oil/filter changes. What recommendations do u hv? Also i did change to a drop in K and N air filter. Thanks

If it was my truck, this is what I'd do.
1.Change all fluids & filters - engine, transmission, transfer case, and differentials. New filters. Personally, I like synthetic oil, but lots of others will disagree with that. GOOD oil is the key.
2. Pull the K&N Filter, and throw it in the fire where it belongs. Put a good OEM recommended filter in.
3. Do a thorough visual inspection from both atop and below the truck. Some things might be obvious (like a CV boot that's split). Check for leaks. Check your serpentine belt.
100,000 - 120,000 is a range where a lot of replacement maintenance has to be done. Don't worry about them, but replace them as necessary.

Generally, a well-used "new to you" vehicle, IMHO it's good practice to assume any fluids that are not obviously new and fresh are due to be changed, along with filters. Look at the fuel filter too.
I like to write the mileage on the filter itself, using a Sharpie or similar, in most applications you can do this. But since you didn't buy this truck from me, unlikely this was done. Some people do keep a log of sorts with fluid changes, most garages put a sticker in the door jamb if they do lube service. I have seen people scribe the oil change log on the inside fender well - that last practice won't win you any points at a car show, but for a beater I guess it's acceptable, but I still don't like it.
If this truck has non-sealed front wheel bearings, look into repacking them. Spring for a new inner seal, clean up the old grease, don't wash in solvent, pack well with good wheel-bearing grease, and Bob's your uncle for several tens of thousands of miles.
A neglected fluid that does need changing is brake fluid, it really ought to be changed about every 2 years or so.
Many boneyards have used owner's manuals, usually reasonable. Or try Faxon Auto Literature.
1. Keep K&N air filter. It's great filter and improves mpg by about a mile or so. But never go for CAI with same filter, waste of $$ and drops mpg by 10%
2. Your serpentine belt is due for around 10 000 miles by now.
3. Spark plugs and definitely wires
4. If it's 4x4, you are due: transfer case fluid, differential front and differential rear fluids. Use synthetics, and forget about them from that on.
5. Your sway bar bushings are due. Do NOT replace them with polyurethane ones, use rubber ones. You do not have to remove anything to replace them, I have done mine on the garage floor, easy access with wheels turned out.
6. Cabin air filter is long due. Replace with carbon one.
7. ATF pending on its condition. Use synthetic again.
