Electric tongue jack

[twertsch]

Good morning, Husband has hurt his shoulder and mine hasnt been great since that horse threw me long time ago. And we are getting old. So we are looking to replace our crank tongue jack with an electric tongue jack. Specifically looking at the Lippert tongues.
Lippert offers a basic up-down power tongue jack, as well as one - the Power Stance Electric Tongue Jack - that uses a 2-to-7 pin plug to power the jack off your truck's battery via the truck's 7-pin plug, in lieu of the camper's battery when setting up or breaking down.
I was sold on the 7-pin plug version until Husband asked - is there a true benefit to this 7-pin plug (at an extra $100)? Since we have solar to recharge the camper's battery once at site, and battery should be charged during tow to site via the 7-pin during tow?

I should clarify- my response was, I'll ask the forum because they may know or have insightful opinions on what the benefits of having the 7-pin option to charge off your truck (beyond "my camper battery is dead") would be?

Personally, I would get the one with the MOST features. Even though it’s a simple tongue jack, features like having a hitch height memory, at my age, is a good thing…I’ll take any advantage I can get…

Typically, the electric tongue jack should be connected directly to the trailer battery through a fuse or circuit breaker. This provides the most reliable function.

In this case, the jack is also connected to the tow vehicle battery in most cases. The trailer battery is connected to the tow vehicle battery through the 7 pin connector without additional devices.

Some of the late model tow vehicles have "Smart" 7 pin connector systems. The tow vehicle computer turns the 12 volt supply to the 7 pin "off" when it thinks it is not needed.

Battery Charging:

Keeping the trailer battery charged is a separate issue.

Fully charge for 14 to 18 hours using shore power for best starting results.

4 to 6 hours of generator charging can keep batteries charged above 80%.

Driving 4 to 6 hours may keep batteries above 80% charge depending on tow vehicle systems.

Tow vehicle charging varies a lot between different combinations. It may or may not keep the battery up depending on how you use the system.
