While I try to avoid it for the front wheels - I don't sweat it if they need to be off the ground. Being level is more important (and more dangerous not to be with an RV (absorption) fridge running)

I've never seen 'ball bearings' be the reason cited.. and can't picture how hanging with just the weight of the tire can be worse than the pressure of a 5000 lb axle...
From storing cars in the past the recommendation was also letting the suspension hang.

The jacks are designed to hold the weight as well... so that doesn't concern me either (they are holding most of the weight before the tires ever leave the ground...)

I have (for looks more than anything else) slid ramps under the lifted front wheels once jacked up - typically in my driveway of past house which needed to lift the wheels off several inches to allow the fridge to run properly.

I do try hard to avoid rear wheels off the ground - but that is more for losing the 'brake' of the transmission in park - and the parking brake (also a transmission brake). Would have to be very well chocked in front.
