What type of rear door is best on a 4X4?

[Thin White Duke]

Hello.

I am on the look out for a 4X4 which will be shared with my mum.

Now putting make and model aside for a moment which doors are the best/safest to use?

I like the idea of a full lift up door - that is it does not have a separate drop down tail gate.

My mum on the other hand would prefer a traditional opening door (they usually come with the spare wheel on the door).

I think the lift up doors are safer, easier to handle in bad conditions and you can shelter under them.

She has a Mitsubishi Shogun in mind while I have a Jeep Grand Cherokee in mind.

Any advice would be welcome.

Transporting dogs is one of our needs. They don't seem to like jumping into the rear of a 4x4 with a drop down tail gate, hence the need for the door to be out of the way.

My mum is against the lift up doors for some reason, possibly thinking they are more prone to going wrong?
