TSAN
I went with a PVC POLE up the side of my POPUP trailer. Goes up in less than five minutes... I can reach out my window flap and rotate it.
I am currently using the standard BATWING antenna on it which picks up 6-36 digital channels here on the East side of the US just about everywhere we go. The KINGS antenna will mount real easy as well. I have a KINGS antenna here now to use but have never mounted on my trailer. It works real good just laying on top of a step ladder here at the house picking up 8 or so local digital stations.
I have also used one the $90 LOWES big house yagi antenna for about a year until I finally destroyed it by folding it up for transport. That one did a bang up job pulling in the digital televison when camping.
I am not a FAN of drilling holes in the roof - It always bites me big time later.
