My 2001 gmc still has the original spare, never been on the ground. If I have a flat it's usually a nail or screw that creates a slow leak which i find , plug, pump up the tire and continue.
I feel for ya, I acquired an old searay a few years ago, 95 model 220 and I don't like it so I have no desire to use it, but it was free. So at least the only thing I'm out is the parts I bought to get it going.
I have a 1/2 inch milwaukee probably 20 years old and it will turn a 5 inch hole saw with no problem other than when the saw binds up. All you can do is turn it loose. Hopefully the trigger lock is not in use.
