I have an aluminum Exiss 3 horse slant gooseneck that I want to add batteries to so I can run my jack and lights when not plugged into truck. Don’t know where to start. What battery box, what batteries ? Walk me through this folks. Thanks

Batteries as in plural ? Start by considering two 6 volt golf cart batteries in series to get 12 volts. This avoids having to match batteries and their self discharge cycles. The RV folks have thrashed this topic thoroughly.

First question is how long do you want the battery(s) to last. Is it just to raise and lower to get the trailer on your truck and lights to load supplies or are you needing them to camp? If camp, is it an overnight or extended time? Will they need to supply power to any other devices (furnace, etc.)?
If it is minimal use one 12v deep cycle battery would be sufficient. If it is moderate use then two 12volt deep cycle in parallel or an extended time two 12volt in parallel or two 6volt in series.
You will need a battery box or battery shelf to put the battery(s) on. It would be easiest to wire a female plug (similar to what is on your truck) to the battery(s). Then just plug the pig tail into the female plug for power when disconnected.
Keep in mind that you will have to manually charge the battery(s) with a battery charger.

Typically when we see batteries on a trailer, they/it will be wired into the "Acc" or "Batt" line. This will let them power your lights while off of a truck, and then charge back from the truck automatically.
As mentioned above, 2ea 6 volt can be a good option, but regular 12V RV/Deep Cycle are by far more common in horse trailers.

I personally like to use the RV/Marine Deep cycle from the auto parts store, because they are cheap. they might not last as long but typically a group size 31 is under $100 real deep cycle batteries tend to be over $200 I typically get 3 years out of the autoparts store type and 4-5 years out of the deep cycle batteries, so I have a hard time paying double for an extra year. That said I dont use mine in hard core rv use, typically for winches, jacks and to run my refrigerators while traveling. I would highly recommend a small solar system no matter what type of battery you install, becaue the better maintained your battery is the longer it will last no mater what type you buy.
