I don't think you will find anyone to do a credible job on a window air conditioner install, but maybe you will get lucky. Roof top air, if your Scamp
is designed to support it, should be a very doable job by pretty much any RV repair shop. If you don't know if your Scamp
was designed for roof air, give Scamp a call.
Orlando area has to be full of RV repair people.
If your Scamp is older, chances are roof is not designed to support an AC. Scamp will know.
