I wouldn't want a trailer, and unless the cart/trolley folded down into practically nothing and didn't weigh very much, it would be impractical too.
Oh I see what you mean. Why not attach a pair of small caster wheels to your panniers plastic backing. They are small enough not to interfere with the rack as long as you position them correctly. Then buy a MEC Terabyte luggage retractable handle and screw it to one side of the front rack low rider and snap it on to your pannier. Voila, you have a carry on bag with wheels. To strap a second bag, use a momma hook ( giant carabiner) and a bungee cord. In fact, I am making one of this on the MEC shopping bag and bought all parts from MEC except the wheels and momma hook to make one. Purpose. Easier to drag around shopping at Safeway.
