Truck sitting

Just wanted everyone’s opinions on a truck that’s been sitting. To this day it’s been sitting since March 2023. The first six months I cranked it a handful of times. Maybe drive it around the block and back. Then I started cranking it once a month. There was a time where it didn’t get cranked for 3 months. Now I’m wanting to get back in it this summer and run it again and I’m in the habit of cranking it twice a month and driving it around the block and back. The truck is extremely well taken care of. Always changed oil every 10k and I’ve followed all advice of care and maintenance from this forum. It’s a deleted truck done by someone everyone knows on here. So the best in the biz. I’ve added octane booster to the fuel. And before sitting it had an oil change. I guess it’s my paranoia from me wanting to make sure this thing is at 100% but is there anymore I can be doing?
Just collecting everyone’s opinions. Thanks.

If it matters it’s been sitting in Georgia climate.

You've been starting it and driving it periodically so I think it will be just fine.

Yeah I was thinking so too. Just wandering if there was something more I could be doing to keep this thing going.

Aside from the engine itself you probably want to inspect anything with rubber, especially with the heat down there. In the same vein all your air lines, fuel lines, coolant lines and wiring warrant inspection for cracks, weather and pest damage. Maybe test the intake for boost leaks. Batteries and connections/grounds probably need a little TLC. Might also want to watch the fuel. Tanks sitting that long, regardless of additives, probably have some amount of moisture or biological buildup. Otherwise a full PM - oil, filters, grease, cabin air filter, etc... - would be the last thing I do before putting it back into service.

One specific thing I've had problems with when my truck sits over the winter months is the HVAC blower and the engine fan clutch. Both have (presumably) built up light rust over the downtime and may get hung up/stuck. Both were easy to remedy when encountered, but it's easier to check ahead of time instead of having to deal with it unexpectedly on the road.

Oh, almost forgot, windshield wiper spray nozzles can collect dust and dirt and may need physical cleaning or replacement. Sometimes it's the little things that go unnoticed until you need them.
