Why are you hauling so much stuff that you need a trailer to fit it all?

My commuting panniers are a smaller set of touring panniers intended for the front. I can fit a whole week's worth of work clothes in one, and a whole week's worth of lunches and snacks in the other. Plus library books, (an occupational hazard). I can't imagine why you'd need to haul more than that on a weekly basis, let alone daily.

I pull a trailer for work. It makes me considerably less maneuverable in traffic. Shifting over for left turns requires patience, planning, and great big balls. I can't just slot myself between two cars. The arc of right turns is limited by the rear wheel contacting the trailer tongue. (Our trailer is designed to clear 26" wheels, not the 700C that I run.) I end up doing the "semi swing", pulling out left, before swinging right in a wide arc.

Dodging potholes is an order of magnitude more difficult as well, since you have to calculate for wheels in three lines, instead of only one. And every bump, manhole cover, wave in the pavement, and transition from uphill, to flat, to downhill creates bucking and chucking from the trailer.

Not to mention that doubling the number of wheels you have on the ground doubles the potential for flats.

Oh, and let's not forget how much wind it catches. You know those gales off Lake Erie that you struggle through now? You want to yank a trailer into those? Or give the crosswinds something more to work with? (I have one bridge where the winds can make me change lanes even without the trailer.)

I don't mind pulling the trailer for work, but I sure wouldn't want to do it daily in rush-hour traffic.

Just because a thing *can* be done doesn't mean it *should* be done.

YMMV.
