I have and use the GM one. She is good for a motor cycle tail bag which takes care of me for a 5 day trip. Leaves the rest of the storage space in the Sol for the wife.:devil: Do a forum search of GM Luggage rack and you will find my thread with pics that show it in use. It is one of my favorite mods and when traveling on longer trips with the wife it really makes a difference getting a bag on there. Also look up " How to pack a Sol":thumbs:
I agree with Gareth. I bought two roll top kayaking bags (in yellow to match my car) and with a bungee net ... it's great for traveling. One guy called it my jet pack and another joked it was my parachute ... all in fun!
