Oh, I see you're on the coast. A little ways from Medford, Redding, Sacramento, SF, etc. How often do you make it to a bigger city?

I could prowl around for a good $50 to $100 trailer around here, and ship it (or perhaps other BF forums could find one). But, it seems to cost $50 to ship just about anything... so then you've just doubled the cost of the trailer, and you rapidly approach the cost of new.

For example, here is this Burley.
BURLEY Bike trailer - like new

It is probably an older model, USA made... well, made right here in Eugene. The "Cadillac" of bike trailers (from a decade ago). Apparently no stroller attachment on that one.

Burley has a unique plastic chainstay/seatstay hitch. I find it is very secure, and relatively easy to attach/detach, and no need to mess with your axles (although I'm now running a right-sided rear QR).

Cheaper ones do show up from time to time, but one can't predict exactly when, or in what condition.
