I just did this prior to leaving for Fl. I had the tires rotated on the toad about 2 weeks ago, and stopped down to recheck the torque prior to taking off. The new aluminum wheels (I say new although they have been around for a long time) do allow the lug nuts to loosen at times so it is important to recheck torque after a while, 100 miles sounds about right.
The point of my thread though is to check them during your pre-trip check you should be doing on your MH. It does not take long to check for a condition that would allow the whole wheel to come off.
