Welcome to the forum Westone,
I can't comment about the antenna issues, I didn't get a TV and haven't used the antenna.
Totally agree with you about the terrible placement of the tiedown spots. I understand it's a very tight spot, and because I was a bit lazy when tieing down my ATV I allowed it to bugger up the sink cabinet. Fotunately I got lucky and the damage was minor.
I have a full size dresser BMW bike which I hope to be able to tow. A wheel chock will be a must. Crossing my fingers I too can may it work.
