Although I own a 2006 Wrangler that is towable--I am not that familiar with the rest of the Jeep line. However, in addition to the issue of 2-wheel drive vs 4-wheel drive, there is also the issue of having a transfer case with a true neutral shift position. Seems that recently, Jeep came out with several 4-wheel drive models with only 2 and 4-wheel drive positions--no neutral. Sure some one with more Jeep knowledge will chime in.
