I just had a 2inch reciever class2 hitch installed so I could try my freinds jack rack. I need to take my bike to the shop,but my trailer is snowed in. Plus I really want one of these racks so that when I want to go for a ride I can skip the hour it takes getting ready and I can travel safely with my bike.(my trailer is very old) I just searched on the net and it stated that the rack needs a class 3? Anyone here have an opinion on this rack and its use with a class2?
