Are the 1200 lb. bars stout enough for the "published" tongue weight of 1100lbs.

Spring bar capacity should be based on how much load transfer you want to achieve.

Since 2010, Ford has been specifying that the WD bars should be adjusted so you restore only about 50% of the load which was removed from the front axle.

If only 50% of load is restored, the WD bars only need to be rated for about 50% of the tongue weight.
If you plan to use the outdated approach of restoring 100% or more, the WD bars should be rated for 100% of the tongue weight.

In a different thread, you indicated the new trailer would have a loaded weight of 9000#.
If that's the case, a reasonable TW% of 13% would give a TW of just under 1200#.

If you want to go with 100% front axle load restoration, the existing 1200# bars should be okay.
If you want to go with 50% FALR, you could stay with the 1200# bars or switch to bars with a lower rating.

I'm curious..
What is your source for using 600 lb WD bars for a 1200 lb tongue when doing restore of 50% of weight removed from front end of truck? My understanding is that you size the WD bars by tongue weight and then adjust properly to get front end of TV to the right spot.
