Stronger Hitch. One has a tongue weight of 550Lbs Max, the other is 1000lbs.
Your trailer has a dry hitch weight of 280Lbs, so you should be ok with the 550Lbs. If you had a tongue weight close to 550 or more, then you would need the 1000lbs.
Being that they are the same price, I'm not sure why you wouldn't go with the 1000lb either unless it's too strong for the frame of the TV.
