True enough, but.....
I guess it couldn't hurt, but if you're going to go through that much trouble, why not just go ahead and replace them? Use dielectric grease on the boots and anti-seize on the plug threads. Doing that will insure you can get them out easily next time.
Tip: Just like coolant hoses, always twist the plug boots to break them free before pulling on them and you'll find they will come off much more easily.
Considering you live in AZ (assuming your truck didn't come from rust-belt) you shouldn't have much trouble changing the plugs. All but one of mine are GA trucks and changing the plugs was a piece of cake.
Anti-seize compound is applied to the threads. the end surface of the threaded body of a sparkplug is flat and nearly flush with the surface of the combustion chamber - a location where anti-seize compound is not applied, and even if a small amount of A.S. compound was applied, it would burn off quickly.
Those deposits are what you are disrupting when removing sparkplugs. It's up to the owner to determine just how tough a sparkplug will be to break free and remove. For MY money, it makes more sense to break the sparkplugs free at shorter intervals than are recommended by the manufacturer - at least once every 30,000 - 50,000 miles.
The auto manufacturers may say that service interval on the spark plugs is 100,000 miles If you read the sparkplug manufacturers own recommendations, they'll tell you that there's a BIG difference between servicing a sparkplug ( the periodic loosening of the plugs) and the actual life of a sparkplug (when they should be replaced).
And I can pretty much guarantee that having to helicoil a sparkplug hole in a head is a lot more work and much more expensive than loosening the plugs by a couple of turns and then reseating the sparkplug 30000 - 50000 miles. And my vehicles that have lasted longer than 400000 miles (76 Buick Skylark and 87 Volvo740T).
But that's just my opinion and my vehicles.
One last point - the climate where we park our vehicles at night does not by itself make sparkplug easier or tougher to remove. That is more a function of how well each person/mechanic tolerates seasonal temperature extremes. I've not only lived in AZ.
