I have to disagree with the trailer being lightweight. I have to say that the u-haul trailer is over-kill for an FFR, because it's designed to carry all vehicles up to 1/2-ton pick-ups. The u-haul trailer has an empty weight of 2000 pounds!!!

That's over-kill for a 2300 pound car. I'm sure that there are 1000-pound trailers that will do the same job for the FFR.
The u-haul is extra long too. To put the weight on the trailer’s tires and not excessively on the tongue you need to load the FFR backwards. This will center the engine over the back trailer wheels. (Although I’m sure this isn’t good for the windshield and wind-wings at highway speeds.) If the trailer allowed you to anchor the FFR 2 feet further back, it would be better.
So, what’s my point... I guess all I’m saying is that if I were to buy a trailer specifically for an FFR, I wouldn’t get the u-haul type, but it’s fine for a general purpose car trailer.
