Even better: lockout hubs at each corner.
Further checking appears even with transfer case in neutral rotation of rear axle will try to rotate front differential. Consequently why towing 4 down is approved. If I want to use dolly will have disconnect rear drive shaft and reconnect when ready to use.
For Smart car appears only way to be sure not to cause damage is to load Smart car backwards rear wheels on dolly. Will have to lock steering wheel with seat belt would have to anyway no matter tow forward or rearward.
Now for both vehicles can leave them in park and remove the key so no need of battery disconnect.
Will have look further into towing Jeep 4 down as wife does not like idea of me connecting and disconnect drive shaft all the time. Currently Jeep front number replace with after market for wench and has taps for D rings. Perhaps they can be used for tow bar. Will look into that as well.
Again thanks for the help.
