Note: We're assuming your trailer uses 12 Volt. As a suggestion, pull its dome light cover off and test with 12V tester. If 12V bulb, continue with below....
Here's some step by step items:
Visit your local RV dealer and buy an RV Battery box. re:

While at the RV dealer, ask to see their many PUPs that have their own onboard battery box (which is often on their tonque area). Thus, giving you a visual of its frame supports as well. re:

Within your PUP, find its 120V->12V convertor. Its hidding somewhere in a lower cabinet or under a bed. The convertor looks something like

The rear of this convertor has 2 x 12 Volt ports on it. These ports (holes for thick wires) are often RED (for "+") and Black (for "-"). The "live" RED thick wire goes to the trailer's 12V distribution panel. The Black thick wire goes to trailer's 12V distribution panel and bolts on its steel side. Or, it may go to steel frame. Regardless, the RED thick wire is the one to focus on.
From Battery "-" post, run a thick wire to frame ground. Use a thick 8 guage wire. If over 10 feet long, use thicker 6 guage wire.
From Battery "+" post, run a thick wire into a 50A (or 40A breaker). This breaker is often 12" from the battery box.
If wondering, circuit breaker is

From the circuit breaker, run thick 8 guage wire into the RED port of the 12V convertor. This can be "sister" spliced onto the thick convertor wire or if Convertor port hole is large, also push its wire end into the port. Then, clamp down.
Note: I would install a simple manual off/on switch between circuit breaker and the Convertor. If I want the Covertor ON (using shore power) and NOT over charging its downstream 12V battery, I simply turn this manual switch to OFF. Or, if I want to 12V battery to feed into my trailer's 12V distribution panel, I turn its 12V switch to ON (when shore power is OFF). A nice manual switch is

If wondering, the battery switch on my seasonal site TT is

For a visual, simply "draw a diagram" of the above wiring. re: Ins/outs and its frame ground contact points.
Hope this helps....
