How much lift do you have? Driveshaft angles get worse with additional lift, which can & does cause U-joint breakage and other resulting carnage (imagine what would happen if the front-most U-joint broke, letting the driveshaft drop to the ground and jam into the asphalt, at 70 mph).
For several years I towed in T-case Neutral in 2nd gear, as the Samurai owner's manual recommends. But the stock T-case shifter locks the front and rear output shafts together in neutral, spinning the front, steeper driveshaft from the rear -- NOT a good thing at 70mph!
Now, with a small-ish 2" lift, I've installed twin sticks to get a true (2WD) neutral. The front driveshaft is now disconnected from the rear while being towed. The TrailTough disconnect would still leave the rear driveshaft spinning, so at really steep driveshaft angles (i.e. large lift) disconnecting the rear driveshaft at the rear flange is _always_ the safest method. They're mostly trail rigs anyway, so it's pretty reasonable.
I've towed 4-down for about 45K miles these two ways since 2004 (towed to Alaska and Newfoundland from LA). I still stop and run the engine and transmission through the gears every 200 miles or so (while gassing up), as Suzuki recommends. It is not necessary to drive the vehicle, just run through the gears with the T-case in Neutral to stir up the transmission oils and splash-lubricate the internals.
