Slow Landing Gear:
1) Low Battery Voltage
2) Bad Ground
3) Lack of Lubrication on Jack Screws and Pinion Gear
Also different manufacturers and models have different gear ratios depending on intended use. Landing Gear on larger campers have to lift more weight than on lighter ones and need more "turns" for a given length of travel for strength. More course the thread the faster; more fine the slower lift for a given motor speed.
