Proper setup of the 5th Wheel on asphalt?
I have always been told that when parking the unit on asphalt one must put blocks/pads under the stabilizers. Does parking without cause the asphalt to sag/dimple? Patti asked a couple of days ago why...

I believe the quote is for tires not on the vehicle.
I don't see what difference it would make whether they were mounted or not.

"Long Term Tire Storage & Care
Long term tire storage, or storage of seasonal use recreational vehicles requires special preparations. RVs should be raised on blocks, so weight is removed from the tires. Storage should be in a dry, cool, sealed garage.
If blocking is not possible, tire pressure should be increased 25% from inflation required for the loaded vehicle. The RV/trailer storage area should be level and well drained. Care should be taken to avoid prolonged tire contact with petroleum based substances: oils, fuels and asphalt. This can be accomplished by placing cardboard or plywood between all tires and storage surface.
The RV should be moved every three months to prevent flat spotting and ozone cracking at the tire sidewall flex point. Flat spots usually disappear, when the tires warm-up, after a 25+ mile drive. Flat spotting, which occurs on vehicles not moved for six, or more months may not disappear.
Tires on travel trailers, fifth wheels and cargo trailers stored outdoors, should be protected by opaque covers to prevent damage from sunlight."
Looking at several tire makers websites says much the same about storing tires on a surface such as asphalt or surfaces contaminated with oils/grease or fuels.
