Does a '95 not have slide-off drums?
I was just inside of my dually rear brakes last weekend, it's a 1995 and the drums definitely slide off. You are in California, so they shouldn't be stuck on, but just in case they are, be patient and use the extra holes in the drum as well as the holes for the studs to apply the penetrating oil of your choosing and they will come off. There’s also a couple of pins that are used to align the wheels to each other. It’s not complicated but if you note the clock position when you remove them, it will make it easier to assemble.
Similarly, do a quick search on valve stem hoses and valve stem adapters and inspect what you have to determine if you want to change or freshen up any of that stuff.
Lastly: all the parts are heavy. Find a young guy who likes to watch/help/learn (perhaps drink beer?) as ten ply tires and steel dually wheels ain’t lightweight. Tightening the lug nuts is also a job best suited for a young man. If you’re healthy: have at it. My back always reminds me that I am now past halfway to the century mark.
Double lastly: While it's completely unnecessary, I like to paint brand new drums as I grew up in the crusty midwest where they rust before you've completed a brake job.
Inspect everything as you go, take your time if you can, and enjoy doing it yourself.
