"A Class" drivers door

I have been asked from time to time what are the pros & cons of only having 1 drivers/passengers door at the front depending on whether left or right hand drive or even no door at all.
This is a question for all you "A class" owners, what are your views on this??.

I don't have an A class, I have a D class.

Don't have a problem Mark, we are happy with using either the cab door or the habitation door.  Don't understand the question really as you just get on and use what you have, how you want to use it.

We have two front doors in our A class and use them when travelling but when on site and lounge is made up they are locked and totally useless as we cannot access them from inside.

Haven't got an A class but if I did I don't think one door plus hab door would bother me but just having an habitation door would, you need a second emergency route out of there just in case.
But personally I would prefer two door plus the hab door

When I say we cannot access those in our m/h I mean the seating is put in place, but it takes seconds to remove so not totally inaccessible, or just step over the seat and you ready for the off.

Don't have A class but I mostly use the habitation door as it is easier to get in and out of the motorhome that way.
