Concrete driveway thickness??
I would like to park my motor home on a driveway that I believe is about 3 inches thick of concrete. I have a diesel pusher that weighs about 29,000. The greatest single tire bearing weight is 5500...

Add me to the list;
Concrete highways are 12" thick. A 4" highway wouldn't last 24 hours with any real traffic. Heck the 12" ones don't last around here. I'm not a fan a the thump, thump, thumping concrete highways for our part of the country. In the south, sure. In the freeze/thaw areas, not a good idea IMO.
When we built our garage we went with 6" thick, 4000# mix with 1/2" rebar on 12" squares topped with mesh holding the in-floor heating tubes. When it had cured we then did relief cuts so there is no span greater than 16' without a cut.
We live in a heavy freeze/thaw area, the garage was built in 2001. The floor looks as good today as the day we poured it.
With that said, I wouldn't expect good things to happen parking a DP on a 3" slab, but maybe.

I had a brand new driveway put in last year, went with 6" thick, re-bar and mesh reinforcement and also added drainage around the perimeter to keep water from sitting underneath the slabs and freezing in the winter and damaging the concrete.
My previous driveway was supposed to 4" thick. However, when it started to breakup into pieces, there were places where the slabs were barely 2" thick. Turned out that whomever poured the previous driveway cheated on the concrete. As someone else mentioned, how do you know for sure? On my new driveway, I WATCHED them pour it. So, I know.
