Jacking Twin axle with four wheel mover fitted

Hi Folks new on here and already asking for help?  I want a hassle free way to jack my twin axle, mainly to spin the wheels to fit the two alko locks.  A scissor jack worked ok on my driveway but seems flimsy.  My trolley jack binds on the bars of the movers when i try to lift it and I'm told by Al-Ko that the mover will impede the pre-drilled holes for the al-ko jack or or ko-jack.  Ideally I could do with something that fits on the chassis leg between the axles although I Don't know whether drilling extra holes in the chasis legs between the axles is a good idea. Can anyone advise please?
