When my wife and I camp with my daughter and granddaughter, it makes
things SO much easier when they can go up and down a small aluminum
ladder I carry for that purpose. The step would be better in some ways,
I think, but the ladder is pretty foolproof for a five-year-old on the
way down from the top, and besides the ladder was free.

I don't carry it unless they're going with us, and it bungees
vertically behind the passenger seat (at the ceiling, just so it
doesn't fall over in transit) if they are.

We can get up and start coffee and whatever without considering whether
the cabinet lid is available for climbing on.
