There is a little wrench type tool that is made for that problem - made by Ken Tool & others. I have one, up in the new shop. I'll try to get a picture of it tomorrow. The problem is not new. Its a real problem when you have several, all on the same wheel. It consists of a 1&1/2" hex ring with a short tail on it, that has a dog leg in it. Drop it over the outside nut and screw the other out of it. Or, when you become aware the inside is turning, you drop it on the outside lug, to keep it from turning, while you go back and tighten the inside.
If your going to have these trucks, you need a big hand full of extra NEW lug nuts. The books will say Don't, but many Owner/Operator types will use oil or antisieze compounds on the threads. Always clean them first with a wire brush. My rule is that if I can't screw on the nuts, easy, by hand, change them out. Nuts are cheap. As above, a time consuming problem/PITA. Also, not all truck & tire shops, know what they are doing. That is scary when they have one of those big air wrenches! Good policy, in self defense, is to learn to do your own wheel & tire work
