Sorry for the posts lately, but I want to get this right. I'm looking at two different TT's. One is 4500lb with a 450lb hitch weight, the other has a front kitchen with a 5500lb weight and 700lb hit...
not sure why the 1000lb tongue weight gave you issues with the 2500HD. We have a silverado 2500HD towing a Outback 295RE with 1500lbs on the tongue (measured with a sherline tw scale) when I'm full of fresh water, or coming home with grey/black. Even DW will drive, handles great, tracks great, even winds and passing trucks aren't a concern. Did upgrade the factory reciever to a Reese Titan, and use a Reese DC WD hitch, but that's it.
