Axle-mount bike trailers w/ GMAC?

[FootprintHero]

I'm converting my bike with a GMAC from Grin Tech. Are there any axle-mounted bike trailers (for touring) that are compatible with the GMAC? (Have included photos of my rear axle, pre-conversion)

If not, I'm open to a seatpost-mounted trailer but have had trouble finding one available in the US...would love some rec's if you know of any.

I have the 8TGMAC motor in my RV-2 velomobile. The velo came with QR 406mm rims. I had no problem mounting a axel mounted hitch for a Wike flatbed cargo trailer on the axel. However with the 406mm (20 inch wheels) The trailer was very much nose down definitely not anywhere near level. Solved that by moving the hitch arm from the top frame rail and drilling holes for 3 SS 3/8" bolts and nylon locking nuts. By the way with the GMAC motors torque arm, I would recommend also using a couple of hose clamps with a piece of shrink tube over the bands to prevent paint damage to the frame. Because of the reverse torque from the REGEN braking the arm came loose and sheared the motors power cord.
