I know there was recently a discussion about the Telestep ladder and the folding one at Camping World. I think I found the best of both worlds at the Container Store. They have a VERY light weight aluminum step "stool"/ladder that's on sale for another week. There are three sizes and they are VERY strudy and as I said light weight.
We just purchased the medium one which is five steps and will easily fit in the basement of our Monty. I can also reach all the windows and even the front end cone. The link is listed below although they don't show the largest one.
