You have to remove the driveshaft if you use a tow dolly, and you can not back up with a tow dolly. 12 & 14mm combo wrenches and a ratchet strap to tie it up (with forward tension to hold it in the tcase) are all you need. The a/t has no neutral position in the tcase (or at least, no detent for neutral), and while it's possible to "balance" the shifter in a neutral position between 4hi and 4lo, any little bounce and it can drop into gear.

I think you can rent a flat bed trailer to haul it, which is what I would do.
