it is not advisable to flat tow any vehicle without removing the drive shafts. the transfer case will have the exact same issues as an automatic transmission as it will lubricate most of the internals just by spinning but the proximity of the clutches to each other or the differentials will still cause heat buildup and oil degradation on long trips. I flat towed a 4wd stepside across the country but pulled the drive shafts from the axels and tied them up to the frame rails for storage.
