Yes, weights and tow and curb weight and GVWR can be as confusing as when my wife says, "nothing" is wrong when she's not talking to me!! (But I've learned that when she says we need to talk I'd best just sit down and listen!!!) :-)
As an engineer, there's rarely a cut-and-dry answer to most things...."it depends" answers a lot of questions concerning weight, what tires are "best", tow stuff, etc.
Hey, I should use that when my wife tells me we "need to talk"....maybe I'll answer, "it depends"
