I bought the Giantex platform on Amazon and am pleasantly surprised.
It is just the right height, making washing/drying hood, roof, front/rear glass much easier. The doors clear the step, so you don’t have to move to open
It is truly non-slip. Even when wet and soapy, I know I’m safe from slipping.
It is solid. I’m 240 lbs and there isn’t the slightest wobble or instability, made better with the four legs and their broad rubber bases.

That looks like a great help. Just wish it had telescoping legs so maybe it could go up another 19" or so to get the roof.
