Hello Joel,
RF amps could be contracted out, doesn't always have to be on site until integration. But when it comes to DSP or other programming being on site has serious advantages. I can understand the love for his 5th wheel. Some day we might start doing that as well. Initially only a tiny one, a Casita or something like that. Right now our two large dogs are keeping us from that.
That is a good ratio. Then again people who are willing to move to your neck of the woods are certainly serious about it and must be down-to-earth people. In my experience most of those folks are good engineers.
