After 13 Votes...the Roadstar has not left the starting line...Turbo+2 leads by a nose through the first furlong...
I personally just prefer the look of the Roadstar Bill. To my eye the shape goes with our bikes better. Though with the exception of that one Bushtec model that is obviously Wing-ee they're all good looking trailers behind our bikes.
With both of you riding together, however, I'd still not vote Roadstar for you guys. It's about 20% smaller volume if I remember correctly. If you're going to bite the bullet and give Anne some extra space you might as well get all you can.
Don't bet me wrong. Going from never having pulled a trailer to pulling the Roadstar it seems huge. I've hauled more crap then I'd ever dreamed I'd take on a bike trip. But if you two are going on continental trips together there's hardly any justification for not getting the extra space when you do it.
