Re: GVW of a 1977 Scout
GVW isn't what the vehicle weighs...it's the Gross Vehicle Weight rating. In other words, how much they weigh, plus how much you can load on them (including yourself...lol...), plus whatever tongue weight you are dragging behind them. It determines the emissions class they are in, and it's mostly a function of axle and spring ratings.
My old 77 Scout II with roll bar, accesories, and winch wighed 4450 last time it went over the scales; the 76 Traveler I used to have only weighed 4180 lbs with just my miscellaneous junk in it, but it was stone stock. The GVW for both of these was listed at 6200 lbs, so I could have put about a ton of stuff (literally) in or on both of them without exceeding the weight limit rating. I have a friend with a 76 half cab Scout II with the 4 cyl, and his also has a 6200 lb weight rating, but I don't think I'd want to do that much weight with the 196 4 cyl.
