New rear sway bar 2012 prerunner

I am thinking about adding a Hellwig rear sway bar. Is it worth the money?
I tow a small utility trailer for a motercycle and am looking into buying a 20' camper. Also is the stock front sway bar good enought or should I upgrade that one also?

Any comments?

 

Consider also, Addco anti-sway bars. They are just a bit larger diameter than Hellwigs (7/8 vs 3/4)and a lower price usually. Addco installs easier as well.

I would install the rear bar first and then decide whether to replace your factory front bar with either Addco or Hellwig.
