Sorry, I KNOW this has been covered but can't seem to find it in a search.
I just purchased a 1999 F-350 7.3 diesel 6 speed manual crew cab dually to replace my 97 for towing. I use my duallies for transport with a 40' gooseneck trailer. I can't seem to find the chart that gives all the weight ratings for different trucks hauling gooseneck/5th wheel trailers.
Does anyone have that spec for me?

 

not familiar with that truck, but a quick google search showed me this

hope this helps:
1999 Ford Super Duty Towing Comparison Chart

 

Wow. I'm pretty sure that's exactly what I'm looking for. I searched google as well and came up with everything BUT what I was looking for. It must be in my wordind of my search. Thanks

 

your welcome - glad to help (and hope it's correct )
