Parker 2820 Class ball mount weight?

[ocphong]

Just bought a boat, now looking at F-250/350 or Ram 2500/3500 both turbo diesel and 4 x 4 of course. I know my trailer has 2 5/16 ball receiver on it. Question is what
class (class 4 or 5) ball mount for 2 1/2 reciever to use? GTW is what I'm really looking for. Any help would be great.

It appears that what you need is a Class 5 hitch (>10,000#)
