I have to laugh every time I see this.....Two pages just to tow a Sammi.
With thousands of towing miles behind me (literaly!) I can tell you there is no need to pull the shaft, make sure the front hubs are unlocked, transfer case in 2WD, tranny in neutral, SW.unlocked.
If you are VERY worried, stop after 5 miles and check the temp of things.....every thing should be cool to warm.
Any standard tow bar will work, just have mounts made to fit your bumber and get a step up hich for your tow vehicle. A tow bar doesn't have to be 0deg. but wouldn't go much more than 20deg.
And, if you are super paranoid go to u-haul and rent a dolly...cheap, almost fool proof, and the guys there will check for proper hitch.
Sorry for the long post but I hope it helps.
