When on site and unhitched from car, before disengaging the mover, use a levelling ramp to level left to right. Once happy with this, apply hand brake and level front to rear using jockey wheel. Again once happy, lower corner steadies - job done.
This is how I would do it but I am always willing to accept correction....
HI TAPESTRY,i have a twin axle,i find easier to to go forward onto the leveller with the mover,i put a wedge behind the wheel,you will find it easier this way ,then follow what chris said.hope this helps you. ALL THE BEST ALAN P/T
"What if you have a alko wheel lock. How do you get them aligned."
In essence drive up ramp to find hight require; remember this position on ramp.
Come off ramp and find wheel position where lock will fit, lay small marker stick or coin by tyre.
Back off, then place ramp where the hight is right against the marker and drive up ramp.
Sounds a hassle but in reality with a good team its done in no time and usually whilst still connected to the towcar so as not to use any battery power.[non EHU]
