Actually, if you stop and think about it, if you have manual jacks, it is impossible to even come close to raise/lower the jacks at an even rate - maybe if you hired 4 burly quadruplets, but probably not even then. One or two are essentially always at different heights than the others by the very nature of the operation. The rule for manual jacks is to never, ever let the front get lower than the back and that works for electric jacks too.
I use a bullseye level on the floor of the camper near the door and keep a close eye on it while I'm raising/lowering using the controller. I also keep an eye on the rear jack feet when lowering because my RR has a tendency to lift before the LR. I make paired or individual adjustments with the controller accordingly.
