It's not the compressive strength you need to worry about, it's the flexural strength and bearing strength below the slab. Then add in W/C ratio, expansive soils, improper curing, segregation, air content, inadequate compaction, etc. Long and short of it, there is no one here that knows the answer but it sounds like you did everything right; If the installer held up his end you should be ok.
And the bottom line is that it's guaranteed to crack (eventually). I place slab just like you've stated, wire and fiber added to 4K psi. I also use rod if I sense a problem with the fill. Rods tend to keep everything together longer. No one has reported any problems. For a big truck, bus, or RV, I would place it with 5" depth. That doesn't void that original warranty, either.
Good luck with your Class C and the slab, you shouldn't have any probs.
