Comfortable towing vechical

I agree - might help on a park wet grassy area - but if otherwise you are not heading offroad, a diff lock will be a waste of money and not much use.

no a diff lock is not the same as traction control ........ though under some situations they perform a similar function

The OP may also be really looking for a vehicle.
Some of the posts show a bit of a warped sense of humour as well if you recognize the way they write at times.
As said more info = better answers
1 How many people travelling
2 How much do you want to spend
3 How long a trip and where do you intend to go.
4 Preference as to make and type of vehicle

The tilt tray they travel on to do this cost a lot more than $30,000 !

So you say. A Toyota owner?
