First you need to modify your picture to have a maximum 600 width.
Second - you would wire the ground to the trailer frame. If you need to extend this wire with a couple of feet of #4 wire, that is fine. You can buy this at Home Depot, or other hardware stores. Just attach it to the existing ground point, or a new one if required.
You have the drawing correct where the first battery is grounded and the +6 is attached to the -6 of the second battery, then the +12 is attached to where your old battery +12 was connected.
Good luck,

I modified the image size, thank you. The ground cables from the trailer were initially grounded to the batteries negative posts, so I was hoping by relocating the ground to the frame instead I wouldn't be doing anything wrong. If the frame will work, I'll certainly go with that because then I won't need to change any cable lengths and will look a lot cleaner. Thank you!
