Installing External Television Mount

[Adony]

I want to install an external television mount like the one shown below to the side of my Travel Trailer that has metal siding. I know it has to be mounted to something solid like a frame member but how do I find the frame member?? I have a wood frame with metal siding and a stud finder won't work on metal siding.. I have tried to find a frame member by pushing on the siding but that revealed nothing..... Any ideas??? The TV is a lightweight 24" TV.

Try going inside with the stud finder.

Now that I have located the stud...any ideas where I can find a powder coated white mounting like the one in the photo?? I have found similar mounts but they are thinner metal and pained black...
