Ladder rack

I have one of these:

It collapses down to a couple of feet and it fits fine in my pass through storage compartment. It really works great and is a very sturdy ladder.

I store mine in a 4" square tube in a lower compartment....easier and looks better too.....Dennis

The ladder bike rack would be good for carrying a ladder. Not so good for bikes. I have one and regret using it for our two bikes.

This is what I use for my 6' alum.step ladder. Works great, never a problem. A small cable lock keeps it safe and a rachet strap to keep it secure.
