The towing capacity of my suburban says 6,000 lbs. Is there a magic formula I should stay under as far as trailer? I've been told to stay around 5,000. We really like one that's 5,400.
If you'll accept the opinion of the owner of your little brother, your towing capacity is 8,400 while mine is 8,600. Not what you say. Your payload capacity is less than my Tahoe's 1,595. Wet...i.e...loaded I am just short of 5,000...and happy on the steepest Sierra Nevada passes...up and DOWN. If you are dry at 5,400 you'll be wet and loaded at 7,000+...and overloaded and unhappy....unsafe.
