odelmer1,
The antenna is the king jack I think they call it, its on most newer trailer now, I had the old bat wing style, they suggest to change it out so the old antenna does not hit on the new flex armor. I just went ahead and let them do it. I had my done in Tennessee, it was near pigeon forge, so we dropped the rig off stayed a couple nights in a hotel and went to some shows, we had a nice time and a good experiance. I had zero leaks, but as I said earlier, that my roof was so old and sun damaged I elected to have them do a tear off and new wood which is much much more thicker than what Heartland puts on the roof. My roof now will out last the rest of the trailer LOL Hope this helps
