I see there is a platform that will hold a bag/small cooler in the area of where a hitch would be located. Does a towing hitch have to be installed to accommodate this add on or is there a more economical/less expensive attachment on the market?
I have the Rivco products ( rack & bracket) on my GW, took about 30 min. to install, and works perfectly. If you have a 2006 or 2007, make sure you get the updated bracket, the original one wouldn't clear the radio amplifier.
Just got the Packit Rak system, took it on a fairly long weekender. We love it. Really lets us keep the trunk free for jackets that need to come off when it warms up. Had the Add-On hitch installed and ordered the Packit Rak with the hitch adapter for it. Easy, easy, easy install and removal!
