No, he maxed out his rear springs. The axle itself is 4800lb rating. The hitch has a 1400lb max tongue w/ WDH. The frame on the other hand is the strongest outside of the raptor's besting even the HDPP's. That's part of the PB's additional mass is its beast frame.
OK. I should have stated he went over his rear GAWR by 39lbs.
Yep. It's bigger everywhere and faster too
Ford uses questionable tactics for their ratings. Take the short bed PB vs long bed powerboost. Same components up front yet the long bed gets a front axle bump of 150lbs going from 3900lbs to 4050lbs. The combined axle ratings of short PB is 8050lbs, the long bed 8200lbs.
My spidey sense says that's due to geometry and physics related to increasing the length between axles.
I mean you can definitely do all that, but you dont "need" to do all that most likely. You aren't doing damage or risking anything by going a touch over the ratings. I really wouldn't worry too much about it. I personally kinda like the bike racks that go on the back of the trailers just for the ease of set up and aerodynamics.
I checked Youtube.
Here's my concern -- Your front axle is weighing in at bone stock truck weight -- no options. My truck empty has more weight on its front axle than you do with ~1500lbs of additional mass. Given the rear tire is the fulcrum and you have bodies in the cab, you've got (spitballing here) damn near 1000lbs behind the rear axle. Something is out of balance on paper at least. You've driven it however. If it's a stable tow, then there's nothing really to change. It's worth investigating IMO. This conclusion is due to the low weight of the trailer axles. If you had ~8klb showing up on them it'd somewhat justify this first swing at the scales.
