it depends on what is loaded in the trailer, if not loaded, but then the pin weight is through the roof. So would not recomend towing one of those without a proper TV that will carry the empty trailer pin weight,
With the loaded weights I see in those units the F250 will pull it but the pin weight will be to heavy, and loaded to GVW the pin weight might be ok but the weight will be to much for any Ford HD till 2011.
But I see many of these towed with DRW's and I bet they could be overweight but the load is not much like a motorcycle and they stay under the load for their trucks.
thats why I am not crazy for these trailers, If I would like a motorcycle I would tow it behind the car in a trailer, that the wife drives behind me anyway.
