I looked hard at the Little Giant, the price was really good but like Fpoole, I was thinking how do I store it. Thought about making a sill similar to what I mounted the glo-steps on but I'd still have to secure it to the outside of the door at the top with a rubber band (tarp strap) and stainless hooks.
I can see I'll have issues with my license plate being obscured (the glo-steps block the plate. I'll either remove them for travel (2 pins and clips) to remove or I'll add an illuminated license plate bracket to the back of the camper. I have a couple nice LED ones in the shop.
I went on an LED kick this spring and changed every incandescent outside lamp on the camper to an LED. Big difference in brightness and with any luck, I'll never have to replace any.
