This is what I used before I purchased my toy hauler. It connects with dual swivel hitch. You can back it up hooked to the trailer. Capacity 1200 lbs.
Since it attaches with dual hitch and does not pivot they call it an 5th wheel extension not a trailer. I've pulled it in Ga. Fla. NC, SC, Ala.Did you use that in Georgia? Reason I ask is Florida Department of Transportation explained to me that this is counted as an additional trailer which is not allowed in Florida, Georgia or Alabama.
I must have spoken to the wrong person at the Florida Department of Transportation or they were having a bad day. They told me if it attaches with a receiver hitch and has wheels it is considered a trailer.Since it attaches with dual hitch and does not pivot they call it an 5th wheel extension not a trailer.
