Can I order a cargo trailer that come from the factory with AC units on top?

I basically want a cargo trailer with a quiet AC unit on top. Quiet being key here. I prefer it come from the factory that way. And I'd like a bunch of 120 volt outlets inside it. It's all I really care about. I just want an office space for remote work and an easy way to tow around kayaks and bikes, etc. I'll live in a tent for sleeping.

Probably looking into a 6x12 cargo hauler.

If not from the factory, I'd guess this is something I can pay any trailer sales company in my area to install? In this case, I'd guess the trailer can come insulated from the factory atleast.

I don't mind finishing the interior.
