The Fox your looking at has a GVWR over 15,000 pounds. That translates into a 3,000 pound pin weight. From my experience AF builds a very heavy trailer. No matter how you try to slice it that is going to put you into overloaded country.
Previous truck was a 2500HD D/A ext cab 4X4. Scaled weight with me, wife, and 80 pound dog with some firewood and hitch was 7500 pounds. I seriously doubt a similar truck even a brand new one will scale lighter. I do know new 2500HDs do have a higher GVWR, but still even carefully loading of truck and trailer, and that aint going to happen as a full timer your goingnto constantly exceed the trucks GVWR.
Why is it so difficult for people to simply get the right tool for the job? I just dont understand why people are so stubborn???
