There are multiple videos on YouTube, some are ok some suck, but it will give you the basics. Hardest part is the oil filter, just wear some old clothes and crawl under the truck. You can get a good angle on it.
1) truck on flat ground With parking break engaged.
2) cold or warm engine, Not hot.
3) be sure you got 7 quarts oil, oil filter, 13mm wrench or socket, rubber glove, paper towels, funnel, oil drain pan (preferably a enclosed oil pan) and you "might" need an oil filter wrench or strap. I prefer the oil filter strap because it's good in tight spaces.
4) open hood and loosen the oil filler cap, it's on the top driver side of the engine, it says "SAE 5w20" right on top of the cap itself. Can't miss it; just loosen it at this point.
5) loosen the oil filter, it's on the front passenger side of the engine. It's a pain, But if you position your body under the truck just right it's not too bad. Remember Clockwise is tightening and counterclockwise is loosening. Turn the oil filter counter clockwise and loosen it, don't remove it yet, just crack it lose.
6)position your oil drain pan under the drain plug on the oil pan and remove the 13 mm drain plug. Be ready for the oil to be coming out very fast at first. It wouldn't hurt to have a piece of cardboard under there. After all the oil has drained out put the drain plug back in and snugg it up.
7) now go back and remove the oil filter completely. Some oil will come out so have your oil drain pan ready to catch the oil. Clean off the oil filter housing and be sure the old gasket from the old oil filter is not stuck on the housing. IMPORTANT- put a few dabs of clean oil on the gasket of the new oil filter. Basically just dip your finger in one of your new oil quarts and then rub your finger around the gasket of your new oil filter. This will ensure proper seating of the new oil filter. Now put it on and crank it down Hand tight.
8) now completely remove the oil fill cap the says SAE 5w20 and put your funnel in the hole and pour in 7 quarts. Be sure to shake every new quart of oil before dumping the oil in the funnel just in case the additives have settled at the bottom. Replace the fill cap.
9) start the truck and let it idle, look under the truck and look for leaks. Do not crawl under truck for any reason while it's running.
10) wait 20 minutes and check the dip stick for proper oil level.
11) I alway look for any sign of leaks over the next few days, spots on the driveway or parking lot.
This may seem like a lot but it isn't, I just included as much detail as possible. Once you do it 1 time your golden.
