What is the rationale around it being better not to do it? For instance, what is the weight on the jack with the wheel touching, which is the weight of the coach/chassis (all but wheel & suspension) on the jack vs. the weight including the wheel/chassis?
Is the difference something like 3600lbs vs 4000lbs? If so, is the extra 400-500 lbs on 7000lb capacity going to be what makes it fail?
The reason I mentioned old wives tale, take a gun magazine. Many, many people won't leave a magazine loaded, because the spring will fatigue, but that's not the way metallurgy works. The act of compressing and decompressing a spring puts wear on it, leaving it compressed (or uncompressed) puts no wear on the spring.
