When and where to get new motorhome inspected in PA\Philly?

Hi, Folks. My wife and I just purchased a new Class C at an RV show in New Jersey. We picked it up at the dealer shortly afterwards and brought it home to Pennsylvania. After getting plates and the temporary registration sticker, I realized the rig has no inspection sticker on it whatsoever.

Can someone tell me by what method I'm to figure when to get it inspected? And does anyone who lives in the Philadelphia area know of a place that inspects them? It's a Class C, so could a regular service station take care of it?

Thank you for your consideration.
