So, my truck has an ARB deluxe steel bullbar, 8274 with rope, no sidebars. Kaymar dual swing-away with two spares meaning a total of 6 BFG KM2s 255/85R16s on 16x7 Steel CSA rims. 125 litre long range tank.
Around town (eg. pretty much empty) it weighs 1103kg front and 1250kg rear. Loaded up for a 4-day trip (food, fridge, recovery gear, tent, chainsaw, 25L water) the rear jumps up to 1722kg.
For longer trips I reckon I'd hit around 1800-1850 but probably no more, there isn't much difference in my packing between a weekend and a month.
