For anyone interested in making their dump bed to be powered up and down, I found a good way. On Ebay I found a WARNER LINEAR K2G20-12V-BR-12 Linear Actuator
that fits just perfect on a 2022 Defender XT to replace the gas strut and make a powered dump bed. You will of course also need wires and a momentary rocker switch to power it. This actuator is rated for 1200# which should be plenty for what you are supposed to load in the unit and what the geometry of the linkage will allow. Several other actuators are higher capacity, but their retracted length is too long. This one fits very well.
