just wondering.... can stock suspension handle a 5K trailer with a 8K truck on it using a gooseneck ? I'm sure it will sag some but, not sure if it's too much for a stock set up
i put 5k of rock in the bed of mine it did set it down a bite but nothing that i wouldnt do again the truck did fine, plus all your weight wont be right over the rear axle
I towed a 12000lb forklift on a 5000lb trailer for 150 miles on the freeway. Scary as chit, but she did it. Lost 5th gear in my NV4500 a week later. LOL
