residential driveway vs motorhome weight
I will soon be visiting some friends who have offered to let me park my motorhome in their driveway. However, I am concerned that I might screw up the driveway with my weight. I am sure the driveway is just 4 inches of concrete on grade with no reinforcement, and I weigh 30,000 lbs (11K/19K). Any thoughts or experience in the matter? Thanks for any input. Dick

Probably not even 4", usually it's a 2 X 4 set on edge which is only about 3 3/8" thick.
Our DSDP weighs about 33,000# and it has broken the concrete drive way up. But we've lived here over 25 years and had several motorhomes. This is the heaviest and it's doing the most damage.

I have cracked my driveway with my coach (33K) when parked and my neighbors when I had to use their entrance to back into mine. I repaired theirs when I widened mine so I could back directly into mine. I feel that a short tag would disperse the weight more evenly, but that's a moot point. If the driveway is 6"(5.5") you would have no problems, but 4" is only 3.5" and it will crack unless reinforced. Hope this helps!

My 46,000 lb MH will sink on a asphalt driveway and I have to put 2X12's under the tires to spread out the weight. It appears to have also cracked my new 4000 psi cement driveway with fiber and I have the weight spread over eight tires so the loading per square inch is pretty low. Just had it replaced again under the warranty. Not driving it on the new driveway again. I will not park mine on a friends driveway. I would feel real guilty if I cracked it.

Not unless your friend is in need of a new driveway and you are buying.

The cement man who poured our driveway said there are two kinds of cement - cement that is cracked and cement that is going to crack. That being said - I probably wouldn't want to be the reason a friend's cement cracked. However our MH was parked on our driveway for a couple of months with no problems.

Our gasser was fine on ours. When we went DP, cracks started showing in the area of the rear tires within just a couple of months....

It will crack it in all most likely cases. Also the age of the driveway. Although cement hardens with age, earlier cements did not have the strengths of modern day cements, so I have been told. Also in earlier days the reinforcement was chicken wire or rabbit wire. Today's reinforcement is re-bar and the diameter is dependent on the thickness of the cement. The thicker the pour, the bigger in diameter the re-bar.
My driveway was cracked and the MH (27k pounds) cracked it more. I had a cement raising company come in and pump & raise all the section That pumping gives it a few more inches of solid stuff when it dries in the weaker spots. But that is not going to help your neighbor until "after the fact."
Just my 2cents!

if ever pouring new concrete and you have a desired parking spot for your RV...have piers put in at each tire resting spot...then have the slabs poured...that will resolve the crack issues from parking

30 years with the WA DOT in construction, design and IT and I've never heard that. Maybe concrete older than that?

Mine was a new driveway with 4000 psi cement and fiber with rebar and it cracked bad. I told him before they did the driveway what I was going to park on it and he said it will be just fine. They did replace it after a two year battle and I am NOT going to drive my mh on it again.

Interesting that some Roman buildings made with cement still stand.

My driveway was fine with my 27ft Class C, But cracked bad with my 37ft Class A Ford V10. The worst damage was where the passenger rear tires rested on the edge of the concrete. My temporary fix will likely be to fill in with a concrete mix or pothole repair kit.
I will likely have to replace at least a few sections of my driveway in the next year and looking for suggestions.
I would like to widen my driveway at least a foot on the passenger side so I won't have to park on the edge. Replace the current 4" concrete with 6". Add piers where the worst damage was on my current driveway. Go with rebar instead of wire. Anything else?
