I ran across this at Home Depot today and brought it home. It was $20 off the regular price.

I haven't tried it on an Ollie yet, because mine isn't built ;( I did try all the combinations in my garage and I am very impressed. It is heavy, but very stoutly made. If you are a large person you will not feel like it is going to spit you onto the ground.
If you wanted to, you could separate and leave at home, the two bottom extension parts and have a very nice lightweight fixed height 3 ft A frame/ 6 ft straight ladder. I think that part would fit in the closet, but I am guessing.
This guy shows all the features.

I plan to carry this fully folded up in the bed of my pickup so the weight is a non issue. I think it is going to be very handy both at home and while traveling with my future Ollie.
Werner makes very good ladders.
