I'm well aware that the corner steadies aren't designed to take the weight of the van and shouldn't be so used. However if I want to raise or lower the front, for example. to allow water to run off when washing can i use the steadies to briefly support the van while adjusting the jockey wheel? So if i want to raise the front I wind the jockey wheel down as far as possible, wind the steadies down to support the front, wind the jockey wheel up and then unclamp it and lower it so the van is supported by it and then repeat as necessary. I hope the explanation makes sense but if not I'm sure you know what I mean.
