Was woundering of everybodys thoughts on this and exprenaces on this. If iam able with my and i was thinking of getting a dual tow hitch so i can put a bike rack on the hitch. Using something like this http://www.amazon.com/CURT-Manufacturing-45792-Receiver-Extender/dp/B00371VLAC/ref=pd_sim_sbs_auto_1?ie=UTF8&refRID=0YT1KD7X54DFK36JTDPA If everything as far as clreance's and weight's pan out do you guys have any reasons why this would or would not be a better reason to carry bikes instead of getting a roff mounted system on the . The one thing that worrys me on the roof system is that i have a A/C unit on it and iam afraird of the weight thing. is a 2006 fleetwood Cobolt with the a 2006 Grand Cherokee. Thanks for the help!!!
