Front levelling jacks on Fifth Wheel

Are the 2 front levelling jacks on a fifth wheel self levelling. By this I mean, can one lift the unit independant of the other or will it wait until both jacks have force applied. I think the one on street side of my flagstaff 8528CKWS will lift camper even though the other one is not yet firmly planted on blocks. Please enlighten me.

They work in tandem.
They lift at the same rate

If they are on uneven surfaces, will one lift or wait for the other to catch up.

As you can see from the rear jacks, they are at different levels yet have the same tension.
When I lowered the front jacks, the street side jack engaged before the other one and started to raise the camper before the second jack became engaged at all. I think that is wrong. I dostand to be corrected.

Yes the rears act independent from each other.

How much difference in the fronts?

i just looked at mine and theres no way for them to be out of sync .... but theres plenty of play within the cross shaft and other gear housing for it to appear that ones lifting shortly before the other starts since the curb side gear housing is direct drive to the motor.
then you would have one gear catch up on curb side then the cross shaft play then the passenger side gear to catch up.
sound logical ?

Sounds logical, but if I have my camper levelled side to side when parking and then disconnect the truck, and lower the front jacks, if one engages before the other, it puts my trailer out of side level. I can't remember this happening before.
