Jack supports and tires while seasonal camping.

So Amy And I decided to go seasonal next year we found a campground we love and I have some ideas on what to expect and what we will need to do for seasonal camping.. I do have a couple of questions though.. Besides the normal stabilizers should I use Jack supports?? If I should how many should I use, and where should I place them on the frame? Now on to the tires I plan On using some sort of composite material under the tires, what Im wondering is should I support the camper high enough so I can turn the tires on occasion.. My concern is the bearings.. Im worried about what will happen with lack of use.. thatnk you guys for any and all input..
