Lippert Rear ElectricJacks

Hello all I will keep this short but going out tomorrow for the first time with our 32QBT and very excited. Little bit of a hassle to get it but when it got here it was ok(besides a new turbo for the truck) ouch ..

I have a question with the rear jacks. Is the whole assembly supposed to slide side to side?

If I can get a pic this weekend i will try to post with the help of my wife...

Thanks and have a safe time...
