I recently picked up a Rivco Rack and rain proof bag from the GL1800 forum. It was used one time and is truly new. It is good up to 35 lbs as it could change the steering on a regular GW. Since we have a heavy trike I put 50 lbs in it and I didn't notice any change in steering or handling of the trike. We really like the rack and being able have a cooler and other "stuff" was nice. It came with the LED stop/turn signal kit which I plan on installing this next week.
