I guess we are in the very small minority who use them. If we are staying a week or a month or longer we will and do use them. If only a night or two we do not. I set them so they touch the gear arm snugly, not tight and use them on our two longest slides. Have used them as long as three months with no damage. Their use, to us, seems to take some more of the side to side roll out of the rig
When you set with them for any length of time you need to check them at least once or twice a week and also keep your eye on your tire pressure. Our fifth wheel is our home so I tend to be more conscious of this than other folks might be.
This is a subject that has alot of opinons-this is ours.
