You didn't sat what kind of TV you have, but if you have a pick up, the bike rack I made here served me for thousands of miles. One of the vertical 2/4's pivots and secures the front wheel with the help of a long bolt and thumb screw. The frame that sits on the bed was made so I could carry "stuff" and now worry about it crashing into the bikes. My trailer had no bumper at all and this was cheap to make and worked great.
