In may I am riding from Pittsburgh Pa. to DC with my Uncle. I agreed to carry evrything. Wer'e staying in motels so no camping or cooking stuff. I have a 2000 Kona Fire Mountian with 13000 miles on it. no front eyelets. I do have a seatpost mounted rack that will take panniers, will it get to heavy? should I try to borrow/rent a trailer? Opinions please.
