I see nothing wrong with that, it sounds like a perfect situation. It needs nothing to use it and although not perfect, it doesn't bug you. If it was your only car and you had to drive it everyday, you would be sick of it, every little quirk would bug you, and you would soon wish you had a newer vehicle.
Things to do:

Buy a cheap camper for it, or a little fishing boat to tow. Go out and do an overnight camp, explore.

Throw an inflatable mattress in the back and take it to a drive in movie.

Throw a cheap dirt bike in the back (or bicycle) and go to an RV Park or trail.

Help move a friend with it.

Go to a local auto show, park it, and chat with the other pick up owners.

Once a year, buy something new for the truck and install it.

Maybe take it to the local 1/4 or 1/8 track and see what she will do....I bet you are the only one with the three on the tree speed shifting gears. Should get you lots of street cred.

Take it to a sporting event, get there early and tailgate. Drop the tail gate down and BBQ....

Go to a Chevy truck forum event or swap meet..

Parking lot donuts at an abandoned box store...

Get a new seat cover, panels, and new carpet. It will seem like a new truck inside..
