Seems you would need a class3 hitch for that, which is not available, as far as I can tell.
What does this setup weigh? Must be north of 3500lbs.
Could have something fabricated, I suppose.
Not sure what the body structure can handle using available mount points. Perhaps some clever welding could spread the load.
I doubt the rear suspension is up to the tongue weight without mods.
Somewhat beyond the tow rating, but I do not know the 'weakest link'. I would guess that the driveline itself is up to the task, with proper cooling. Trailer like that should certainly have its own brakes.
