You will get lots of differing thought on this but this is mine.
suspension have limits on how far they travel and when you lift it on levelers it is very much the same as lifted for service at garages. whether it stays for two hours or two weeks, I see no difference in any, wear or otherwise. I see suspension wear as a factor of how many bounces and movements are made rather than the timing between those movements.
One might make a point that using the jacks for a longer period might put more pressure on the lines, valves, etc. and a weak spot in one might show sooner when left under more pressure but I do not worry that issue much as a weak line is going to fail anyway, so for the convenience, I ignore the small point. Fact is I might prefer a weak point fail while I'm home?
One "Could" avoid the question of the lifted wheel by running that one up on a set of blocks, etc. but is it not a tradeoff for less harm to the tire on the ground which we know is not good for them?
Small points that I have learned to ignore as the difference in long term value is so small that I just assume it as part of the game and maybe only 1% difference for making my life easier and more fun.
