Foldable Steps
We purchased a new (to us) RV. When it is driven the electric steps work fine. but when set up they don't always extend when the door is opened. I originally set up some concrete blocks but worried the added weight would be too much. I decided to make some steps that would break down and assemble easily and also store easily.
Cut the Pieces Needed
I decided to put half slots in 3/4" plywood. I cut 2 pieces as shown in drawings that would make 10" steps and an 8" riser.these are #'s 6 + 7. The measurements are on the drawings for all the pieces. Since I was going to paint these to protect them from the rain, I cut the slots at 7/8" instead of 3/4"
After Cutting Pieces, Start Assembly
Since I hadn't painted these yet, they were a little loose fitting which made it easy to assemble, but were still very stable.
Attach Piano Hinges
Attach the piano hinges as shown in drawing. This makes them fold up neatly for storage.
Put the steps on and try them out. I ended up putting a couple of dowels in the top step and drilled small holes in parts 6 and 7 for them to sit in. This keeps the steps from slipping and moving on you as you use them.
Set Them Up
They worked out perfectly for short term use, and weigh less than one cement block.
