Toy Haulers (TH) by nature are heavy pin/tongue weight empty but that weight will lessen when toys are placed in them by a percentage of the toy weight because most if not all of the weight is being placed behind the axles. That is why they have more DRY pin/tongue weight.
Your two hogs weigh 1600lbs. Putting them in a TH will remove about 400lbs OFF the pin/tongue. A travel trailer (TT) TH may work for you if you only tow with the toys.
More experienced TH owners can confirm or correct me on this.
On Edit: I see you're in Houston. I saw a small TH TT last spring at Ron Hoover down I45 in La Marque that might work for you. No idea what it was but they may be able to help.
