Neon,
We spent almost 5 years living fulll time in our motorhome. While my MH was pretty much standard (Winnebago) I made a PVC mount for our satellite dish that caused the same reaction you are getting. I would sit in the RV and laugh as people, mostly guys would point out my dish and start discussing it. Even had some come knock on the door and ask if it really worked. I found this after I got frustrated with the flimsy tripod that I got with the dish. Once I got the hang of it, I could set this up and have a 95% signal in 5 minutes or less and the wind did not affect it.
Here is a link to it. If you add one of these, they will be convinced you are an alien.

PS
I really wish I had known about this site when we were on the road so I could have done exactly what you are doing now. Would love to have attended several state crappiefest.
good luck
