Gooseneck Coupling Adjustment

[wheatman]

I bought a used flatbed carhauler and wondering about rules of thumb adjusting the trailers gooseneck hitch coupling.



I haven't weighed the axles but looks to me like empty most of the weight is riding on the rear trailer axle (i know this will change loaded) and the trailer bed is not flat on flat ground. How much clearance should i try to allow myself for between the truck bed and gooseneck? other things i should watch for?

when loaded I want my trailers to be 2" to 4" higher at the front of the trailer frame than the rear of the frame



you can get by with 4" to 6" between the gooseneck and you bed if you watch the dips and hills and turning

We load our work trailers and I also load my 5er in an attempt to get the same weight on each axle... to us it doesn't make a lot of sense to have one axle carry 1500 of 2000 lbs more weight than the other... . in doing so. . . we also attempt to get a percentage of the weight on the king pin...

Our work trailers were designed and built to have about 65-70% of the from the center line forward... thus about 15-20% of the total weight is tongue weight...

All our trucks now have flat beds... too many issues with the clearance on a 4x4 and the bed. .
