Well, we're not full-timers, so I don't know how much this response is worth, but here goes.
I'll torque the lug nuts ASAP after a wheel has been disturbed. For example, if I have a tire replaced or a flat fixed, as soon as we get back to the storage building from the tire store, I'll retorque that wheel (and usually all of them since I have the torque wrench out). After that, I'll check the torque after ~50 miles and then again after ~200 miles. If the torque is stable (i.e., no signs of any lug nuts loosening), I'll run the torque wrench over the lug nuts every 6 months or so - usually when I'm checking battery water, etc. I've never had a problem with any backing off after the first couple of retorques after having been disturbed.
