I tried to hollow it out as much as possible to cut down on weight, while still making sure it’s overbuilt enough to support the corner of a 2000 kg pickup truck. I’m planning to use 98 × 48 mm lumber.
Open to suggestions on how to improve it. My only concern is the stop block - it’s not any higher than the previous steps. I could make the tire sit deeper in that “well,” but that would reduce the overall height.

My only concern is the stop block
Chamfer the ramp block edges and widen the gap before the stop block, so that the energy required to overcome the stop block is greater than that to get up the ramp, and it’s more noticeable that you reached the top?
I’ve driven over a steel ramp and it sucks. Out of an abundance of caution, I would probably make the stop block higher than the steps.
Paint it Rietveld style
I have plastic ramps and a smooth garage floor. One time I was using them with a rwd car. When I was going up the rear brake line decided to fail and the car pushed the ramps and ran into my toolbox.
What is that for? When I read ‘ramp’ I thought it was for overcoming some height differential, but 20cm seems like quite a lot for that. And I don’t understand how the stop block would fit in there either.
Most likely for performing maintainence on a vehicle without having to lift it with a jack. For simpler stuff like changing oil it can be easier to just use a couple of ramps instead of a jack and jackstands.
