So here's the breakdown for weight in the bed.
Note: Payload for the JTR is +/- 1,200 lbs.
Leitner ACS forged rack w/extra cross bar: 90 lbs
Leitner XL Gear Pods x2: 100lbs
Quick Pitch RTT: 180 lbs
(Total rack, pods and RTT: 370 lbs)
Maxtrax bracket w/pins: 5 lbs
Maxtrax Xtreme: 20 lbs
HiLift bracket: 3 lbs
HiLift Extreme: 31 lbs
Total load in the bed: 429 lbs
I feel pretty good about the current layout and here's why.
Wheels and suspension upgrade is a wash IMO. Tires are heavier than OEM (285/70R17 versus 315/70R17) at 14 lbs per tire x5 for a net gain of 70 lbs.
Front bumper upgrade is lighter than OEM. The Warn Zeon 10-S is 80 lbs. Safe Xtract S-20000 recovery kit is 35 lbs. So a net gain of 115 lbs for the winch & gear.
The removal of the OEM 40% rear seat for the addition of the Goose Gear seat delete and Engel Fridge (66 lbs) might have gained me 30 lbs.
So all told, with the 429 lbs in the bed, the 70 extra lbs in tires, about 30 lbs for the fridge and 115 lbs worth of winch utilizes about half my payload at 644 lbs.
This leaves room for people and provisions and keeps me under GVWR. But I still intend on adding some White Knuckle rock sliders so we'll revisit this number once I'm done.
