Great question, an "in general" answer.... If you leave the driveshaft connected to the transmission, the output shaft of the trans is going to be turning. During normal operation of a manual transmission the gears splash oil through the transmission. When only the output shaft is turning, there is not a lot of oil being spread through the transmission. Eventually the trans will be damaged.
If your truck is 2 WD then towing with the rear wheels off the ground is not an issue.
If your truck is 4 WD and you can lock out the manual hubs then towing is not an issue.
If it were my rig.... I would disconnect the drive shaft at the rear differential and have it towed with the rear wheels on the ground.

Allow me to qualify something:
If your truck was illegally parked and the wrecker driver snagged it ... or ... If the repo man came and hooked it.... All bet's are off. Neither are going to give a rip about damage to your unit.

Seeing how I have successfully reman my own S5-47,
In neutral when the truck is running and clutch engaged, the input shaft spins the counter shaft in neutral in the ZF S5-42 and S5-47...ergo gear oil (ATF is spec) flies all over. The gear on the main shaft spins off the counter, turning everything. Yolk hooked to assend of main shaft, upon which the syncro bodies ride (where the syncro sliders are ride, then shift forks), will still make gear oil fly around...YET not as much when running. BOTH shafts have fixed items.
My ZF was way borked and lasted eight months of Hell before it died and whined like a ***** before the input pocket bearing gave up towing a vehicle. I would have no qualms pulling it 200 miles if solid and gearbox full (we all swear by 5 quarts). 2000 miles? Pull driveshaft. 4x4? Put the transfer case in neutral. 2x4? Try to grab a flat bed.
PS...shift to fifth before you go to reverse on these, drop right into gear then...they are the same shift slider.
