Have to ask the hydraulic jack guy. If they say don't do it their must be a good reason. Why chance it? A guess, maybe it is not good on the suspension to lift the axels unsupported. Maybe it could tweek the frame or house. If the guy that built them says not to it I'll take his word for it.
The worst that will happen (unlikely though) to the F53 chassis, is that the springs might get re-arched a bit. And that's not necessarily a bad thing. The "guy that built them" likes to speak in generalities with his lawyer putting words in his mouth.
