a couple years ago my husband and I took a tour with Experience Plus, and we loved the pop-up, drop-down to panniers, expandable trunk we had for the tour -- and which we could buy for around $135, if we felt like paying for sporting their logo, which we didn't, although the tour was terrific. Trouble was, I haven't found that trunk. It had bungee cords on top, numerous pockets. a popup expandable top and drop down sides.

The Axion Columbus does seem to be a possibility -- anybody have experience with this? I don't really care about the insulating feature, I just want more room to accommodate more clothes as temps fluctuates, farmers market finds, etc.

Thanks for any and all input!
