I'm a little confused as to weight ratings. My TV (2012 2DR Jeep Wrangler Rubicon w/6-speed manual) has a GVWR of 6232# (per Jeep web site), GCWR of 6507, GAWR's 50%/50% (of GVWR?), 200# Max Tongue Wt, 2000# Gross Trailer Wt. and 4104# curb wt. (all per owners manual). The O/M says GVWR includes driver, passengers, cargo and trailer tongue weight. It also says the GCWR includes 150# for driver, and curb weight includes all fluids and full fuel tank. So in theory I could drive around (without the trailer) with 2128# of cargo/passengers! (6232-4104) This seems a bit high for some reason. So if pulling a trailer, the trailer (plus its cargo) must be </= 2000#, which leaves me with 203# for additional passengers/cargo in my TV (6507GCWR - 2000GTW - 4104 curb wt - 200 tongue weight) Is this correct? Also, since I have installed a 3" HD suspension lift, does this help or hurt my overall numbers? I'm asssuming the HD shocks/springs in both front and rear would help with tongue weight, as opposed to the vehicles original stock suspension.
