Utility Cycling - Axle too short for trailer coupler?

I have a Trek 7.3 on which I'm trying to install a Schwinn/Instep coupler for our child trailer. The coupler attaches to the back axle (quick release). However, it seems that the axle is just barley enough as is; when I add the coupler, the axle will not reach through to meet the nut on the other side. Has anyone else experienced this, and is there a solution? The couple attaches fine to my old junker hybrid, but I'd much prefer to use the new ride for the trailer.
Thanks.

Yep, I had the same exact problem with that coupler on my Electra Townie. I did not find a good solution and had to MacGuyver a hitch.

Some quick release skewers are longer than others, i'd try taking it to a shop, generic skewers are often a little longer to accommodate the beefiest possible dropouts.
