Good move.This trailer is made locally by a guy that's been making them for at least 25 years.
That's 12,168, add in the trailer should be putting ~10% of its load on the tongue (~1400), the rating is only slightly low ~400lbs for trailer max. (not much room for error or comfort, but considering safety margins being built in......)16K is a lot of trailer! Be sure to check the weight rating of the tires. My 14K trailer came with tires rated for 3042lbs per tire, so 12K for all 4 tires
