Mike isn't using it with that big of a trailer in the picture. Looks like his is an open 5x12 (700lbs) That is an old trailer in my photo and it is only a 3500lbs axle. I use a 5x14 now and it's custom built with a tandem axle for SOD when I do it on occasion. For normal mow and go with 2-3 mowers the f150 is sufficient. BTW you're still within limits of a f150. Is it the perfect situation for your setup no it would be time to upgrade. I wouldn't consider your comparison very fair though.
