Just avoid the bed utility package and any sort of bed cover or protection and FX4, as well as the sunroof and payload should be close to 1600lbs.The PowerBoost with the 7.2Kw generator is great for travel trailers. Unfortunately, configuring one with enough residual payload has always been a challenge. Platinum and Limited buyers have been alarmed that their expensive trucks were especially payload limited for towing. I managed a 2WD PB KR with 1800# payload (1787# sticker, 1850# scales).
2024 PB only comes in 4x4.
Buyer beware, a very base XLT and maybe Lariat will have a payload of around 1400#, maybe close to 1500#. The King Ranch and Platinum are both loaded with options- sunroof, bed utility, power running boards, etc. Expect a sub 1400# payload.
