New Steps Needed After Axle Flip - Recommendations?

I built a 30" X 36" box out of exterior grade plywood high enough to make the step up to the first step comfortable. I left the bottom open on the box so I can turn it over in the bed of my truck to carry stuff in when towing. I covered the top and sides in outdoor carpet. It has been a handy thing to have and works great as a bottom step after our axles were flipped.
