Oil leak after flat towing.

Towed my 94 YJ 2.5L behind my RV for about 800 miles, transfer case in N, Auto in N, steering unlocked. Drove it during this time with no problems. Got back home, unhooked from RV and started up to move to driveway. After about 2 minutes strong smell of hot 'something' plus smoke from underneath. Upon checking the exhaust manifold forward of the transfer case and cross member has some sort of oil on it and is smoking. Hosed it down ans sprayed with engine cleaner.
I'm thinking that having the back wheels turning the drive shaft that exits the transfer box for that distance has flushed out some of the oil in it via the input seal, as the cover plate on the bottom of the transmission is covered in oil, also.
What to check first ( after I check the oil level in the transfer case)? Auto fluid is clean, up to level and shows no sign of a problem.
Any thoughts?

Oils leaks are just not normal for a flat tow so there is a problem. Oil leaks down and to the rear so the location of the leak may not always be where you see the fluid collecting. Checking all fluids is a good idea and if you find one low that may be a giveaway as to the location of the leak. A thorough undercarriage inspection with some spray and wipe of choice and paper towels would also be good. You flat tow in N/N so what all turns when you tow. It could have been a case spinning a shaft so the seals are also players.

Doesn't the factory suggest to roll with the t-case in N and the transmission in park/gear?

When I flat tow my '91 in N&N (5 speed though), I have the same thing at start up after a long haul. My t-case seal leaks a little and fluid spins onto the muffler. It always does it and burns off small amounts at a time, so not noticeable. After towing, a larger amount of fluid will burn off at one time once the muffler gets hot with the very noticeable smoke and smell.

Possibly, The leak is at the front of the transmission, not the rear, the muffler is dry, its the down pipe where it goes into the cat converter that is getting the oil leak, and the front of the transmission filter access plate. I agree though, it has probably been there all the time, the 800 mile tow just made it obvious.
