While visiting my son next week, we plan to park our 18000 Lbs motorhome in his driveway. We also plan to use it while we are there, which means I would deploy the hydraulic stabilizers and 3 slideouts. My son's driveway is poured concrete, still I know every driveway is different. I'm concerned about damaging his driveway.I'd like to hear from those of you that have deployed stabilizers in your concrete driveway for vehicles in my weight range. Did anyone end up cracking the driveway? Thanks

Cut some ply wood squares to put under the feet of the jacks.They also make jack pads you can buy for this. You will find some RV PK's require them if the have black top sites.

No one can say whether you will, or will not, damage the driveway.Get some wooden planks large enough to spread the weight over the largest area possible. Lower the jacks as far from the edge of the concrete as possible. Lower the jacks only enough to stabilize the MH in a reasonably level condition. This will allow the wheels to continue to share the load. That's about all you can do.

My rig is 23000 lbs loaded and wet. I park in my concrete driveway, have not used anything under them. 1 yr and I have no damage on my driveway.

Spreading the load between the tires and the jack pads is a good option even if you do have large jack pads. My Bigfoot jacks have a larger surface contact area than my tires, so a I normally don't bother with any boards unless I need them for leveling, but for those with the smaller pads, I think they're a good idea. My 18,000 lb coach has never damaged a driveway or parking lot.

If you are near the edge of the concrete, maybe. If you are several feet from the edge of a slab, no problem at all.

I have used my levelers on my concrete drive without problem, but when I had the driveway poured I had it reinforced for just that reason. As long as there is no air gap under the concrete you should be fine with some shoring boards. But if there is an air gap under there that formed from running water or tree roots then who knows, you may pop right through it.

Why could you not just park it and not use the stabilizers.
