Hi Mike,
You'll want to check the tube diameter of your current manual trailer jack. I'm assuming it's an A-frame style bolt on jack, so know the diameter of the jack is important to make sure you get one that will fit the size of the hole in the trailer frame. If it's bolted on, it should be a 3-bolt pattern, but you'll want to check in case you need to do any drilling to install the new one if it uses a different bolt pattern. Measuring from the mounting plate down to the ground when the trailer is level is a good idea too to figure out what your retracted/extended height needs to be for the jack. You want just enough travel that the coupler gets off the hitch ball without the jack having to excessively extend. Something like the etrailer Electric Trailer Jack for A-frame part # e23ZV would be a good option. It's rated for 3,500lbs of tongue weight so it can easily handle the weight of your trailer, has 18" of travel, and a 2 1/4" outer tube diameter which is pretty standard for this size trailer jack.

We have a 2018 micro mini camper. It came with a power jack which went bad. Called E trailer saw comment above alot oh good advice. We bought the jack shown above was an easy install. Difference for you going from manual to power you will need to get power to it. The jack has the wires to connect it to power g jack has long wires. I have been very happy with it. Your trailer sounds heavier than our camper need to make sure it will handle the weight. People at E trailer can help you with that.
