What are the Dimensions of the Electric Jack # EJ-3520-BBX

Question:

I am wanting to add an electric jack to my Jayco camper. I currently have a hand crank and I can my tailgate when the crank handle is anywhere in the upper half of its rotation. I am looking at the EJ-3520-BBX, but I am worried that the motor and gearbox will interfere with my tailgate. Can you get me the measurements from the mounting plate to the bottom of the motor and the distance from the jack shaft to the hitch side of the motor?

I went out to the warehouse and took some measurements of the Electric Jack # EJ-3520-BBX that you referenced.

The entire head measures 8-1/4" long (including the buttons) and 4-1/8" wide and 5" high. The motor hangs down about 9-1/2" from the top of the head. Without the buttons the head sticks out 5-1/4" from the front of the mast and 2-3/4" back from the front of the mast.

From the mounting plate to the motor it measures 10" and from the mounting plate to the back of the motor measures 14-1/2". The back of the head only sticks out about 2" from the back side of the mast and the side of the motor are about as wide as the mounting plate so you could mount the jack so that the head is pointing a different direction although the light wouldn't be directly over your trailer coupler.

I have attached some photos with dimensions as well as a review video for you to reference.
