Roland add+bike trailer bike

I am reluctantly listing our roland add+bike trailer for sale. This trailer bike is different from other trailer bikes because it allows for a rear seat to mount on its rack, so you can ride around with 2 kids. Once my younger outgrew a front seat, this was the ideal solution. We barely got to use this last summer, and my kids just grew too fast for me to remain comfortable with the weight ratio. :(  My loss is your gain. It's still in excellent condition, and you won't have to wait for one to be imported. I can get more recent pics for anyone who needs them. I'm not selling the seat or bike, just the trailer bike with its rack. Importing new costs well over $500. I'm asking $480. Feel free to ask any questions. Thanks!
