The only problem I see with mounting to the trailer is that the trailer will most likely be under a shade tree and you won't be able to pick up the satellite signal.
We use to bring out all of our satellite stuff from the house when on trips but after the NATIONAL BROADCAST came out with their digital HDTV setup we started using it with the OTA BATWING roof antenna on the trailer. Here on the east side of the US we get from 6-36 local town stations just about where ever we go. This is full blown full screen high def television for FREE to the public. Stopped bringing out the satellite stuff after that.
You might be in a real good spot to get all of the local towns national broadcast channels ABC-CBS-FOX-NBC-PBS all in high quality high def digital TV at your trailer. Then just use the camp site cable for the few CABLE stations you want to watch like CNN etc...
Like us you probably only watch NCIS and CSI anyway...
