A lot depends on the soils in your area and the subgrade you use. 2500 psi concrete is more appropriate for sidewalks. I would use 3000 psi concrete. In some areas with expansive clay soils, rebar and wire mesh may not be enough and post-tensioning works better.
When I built my RV garage, they used a 4" slab with #3 rebar at 24" each way, which is pretty minimal. It's fine for this area even with a heavy coach like mine. It might not be right for your area, so it's worth getting with a contractor who has some experience in this type of work.
I've been in the rebar business since 1980, doing everything from small residential projects to huge projects with thousands of tons of steel. I should clarify that 6 x 6 mesh doesn't mean anything. That's the wire spacing. There is also the wire size or gauge. For example, 6x6-W2.9/W2.9 is a six inch spacing each way with 6 ga wire each way...a common size.
