I have a 530CK that I haul with an older F-350 single rear wheel. The Ford is a 7.3 diesel/5 speed. What 3/4 ton make is yours?? Is it the heavy duty model?? Easiest way to check is to look at the hubs on the rear axle. If the hubs are flat, it is a light duty model. If the hubs stick out 3" or so from the rim, it is the heavy duty model. Is yours an auto trans?? If so, you will need a big tranny cooler.
My break down goes like this:
P/U: 6300 lb
23' gooseneck trailer: 6400 lb (3, 7000lb axles)
530CK: guessing about 12K lbs
That's a lot of weight going down the road! Everything is near maxed out, and my P/U's GVWR is exceeded. I have 16 yrs experience as a truck driver and 1.5 million safe miles.
Where in PA are you?? If you are in the mountainous area, that is a lot of weight to get stopped. You can't be in a hurry. Sometimes I get over a hill in 2nd gear. Whatever gear you need to get over the hill you need to go down the other side in the same gear.
PS. My 530CK will be up for sale in the spring, but hauling it from WY to PA will kill most any P/U.
