More concrete...

Don't want to rain on your parade, but this may help others down the road.

I too noticed the lack of rebar, support blocks to keep the steel off the ground (to prevent rusting) and inside the pour, and the lack of compacted base rock as a base.

Was this job done by a concrete contractor? I hope you don't have the issues the above mentioned components are designed to help prevent, namely cracking, settling and failure of the pad, especially with a heavy vehicle like an RV using it as a storage area.

I just had my driveway widened and they used all those features and added some color to the concrete to make it look like it's been there for years.
