I am looking at buying this rack http://store.summitracing.com/egnsearch.asp?N=115+400024 I know it isn't recommended for heavy items like spare tires and stuff,but I think it wil work for the occassional camping trip where I will only be putting maybe a cooler,tent and sleeping bags up there. My question is,what kind of mounting system do I need to get to mount it to my rain gutters? there is an accessory kit in the link,but I am not sure which I need to mount it to the gutters,the descriptions aren't all that great. I do not have a factory roof rack,so I can't mount it to that. thanks for the help,Ben
