Holy Cow! I thought my one custom trailer was tongue heavy at 450-lbs but 1,500 lbs is rediculous and I don't see how you ever put it on the truck and maintain control.
I would take that trailer and have it redone, don't know what your hauling but waaaaaay to much tongue weight. You could might move the axels forward etc. or put some kind of counter weight towards the rear of that trailer. I can haul right at 10,500-lb on my one trailer that is 22-ft long and 7,000 on the other trailer, which is 14-ft.
