#9 in Tow barFull review
For anyone who lifts the bar on and off often. It is light and complete in the box, at a premium price.

3.5/5
For a compact car behind a motorhome on a budget. Park level to unhook, since the latches can bind under load.

#10 in Tow barFull review
For short or rare tows of a small car on the smallest budget. Regular RV travelers should buy a self-aligning bar.

#12 in Tow barFull review
For a heavy vehicle when you want the brake built into the bar. It is heavy and costly, so weigh it against a bar and brake bought separately.
