Pretty sure the UVW weight published on the yellow sticker is a number derived from who knows where. Some say it's the basic weight, based on some initial weight, and others say it's a number generated via computer based on installed options, etc. Then, others claim it to be a weight derived when the unit was weighed at the end of the assembly line.
The bottom line is we really don't know. The published weight is a nice number to start out with if you're looking for anticipated cargo/hitch/pin weight numbers. When I took my trailer to the CAT scale it came in 160 pounds LESS than the sticker number, but the hitch weight is 90 pounds MORE than the "advertised" number. Never weighed my truck completely empty, but it's CAT weight, with a full tank of gas, WD shank, toolbox in the bed with at least 100 pounds (probably more) of stuff, and myself sitting the the drivers seat, came in only 350 pounds over sticker weight. If I subtract the my weights and the fuel weight then the weight is LESS than sticker weight.
Everyone has their opinion, and mine is that sticker UVW is pretty accurate as long as you think pretty accurate is plus or minus 100 to 300 pounds.
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
