x2 on being GP24. The trailer companies love to provide the Interstate GP24 Batteries. Look on the battery case and give us the complete model number. I think my part number is SRM-24
If you have a multimeter measure the Dc voltage across the two battery terminals...
24VDC batteries are not a normal battery for use with the RV trailers.
just my thoughts
