We bring 2 with us. But we travel with 3 families in a grand gathering reservation. Up until this January, 2 of the families had a class A and we could tow a golf cart behind each one. We actually modified my car trailer to load 2 carts on it 2 years ago, and I moved to a 5th wheel. The one family still has a class A and towed the 2 carts down.
We have looked at the swivel system as well for the 5th wheels, but have not made any move on building 1.
