Good advice Joe. We went through this when we switched tow cars. A nuance example for a manual transmission is that some are lubricated by the output shaft(s) and some are lubricated by the input shaft. Those that are lubricated by the input shaft are not towable (even in neutral) because without the engine running, there is no lubrication in the transmission while towing even though many of the internals are rotating from the output shafts.

One reason that the 4x4 with transfer case works is because you can put the automatic in park to keep internals from rotating without lubrication. Most (but not all) transfer cases are lubricated by means other than the input shaft.

And dont forget to read the 6 keyed notes at the bottom of the sheets. For example who wants to start and run the tow car every 6 hours?
