Your battery is the side-post type
The very first thing you need to do is check your connections
Make sure the battery terminal bolts are tight. Tighten them as needed. You should not be able to move the cables by hand
If you can’t tighten them, remove them and physically inspect them. They’re probably stripped. If so, replace them. Any auto parts store will have them.
Also make sure the battery cables are clean. Peel back the red and black rubber to inspect, as needed
Just how old is that battery? This is the time of year when it gets colder and marginal batteries fall flat on their face, with no warning whatsoever. If it’s more than 5 years old, just replace it, consider it preventive maintenance
If you happen to do get the truck started, I suggest heading to an auto parts store and getting the charging system checked out. They’ll probably do it for free.
I hope you’ve been checking your engine oil level, and topping off as necessary? I’m not making an accusation, by the way
To be honest, I believe your truck has at least 2, possibly more, problems. But the first step is getting it to start reliably. Then we can deal with the sputtering
