I will say that my wife raised Percheron draft horses and would show them and sell them and those nags are all very heavy. We had a tandem axle Moritz stock trailer (GN) and I pulled it all over God's creation with my F350 one ton diesel. Best thing she ever did was get out of the horsey business. Horses are like boats, a boat is a hole in the water you pour money into and horses are the same. I do like the 'gentle giants' they are very docile and easy to handle but we are done. Sold the Moritz and just sold the pickup truck.
I know one thing and that is, your outfit cannot pass a fuel station. Gas and diesel are going up, way up and soon.
