I guess I should clarify that point.

I agree that a car is the best option if its a practical means of transportation in a given situation. But I feel that there may be situations where I may have to leave, but would not be able to use my car.

So, my question is asked in the spirit of "if I were to get a wagon, how about this wagon" not "what is the best transportation in an optimal situation".

I have checked some older threads about bug out wagons but with a family of 5, and a finite budget, some of the other ones aren't too practical for me.
