My Saturn SC-1 and bike need to make a 2000 mile trip together. My hopes and dreams were to add a ball to the Saturn and pull the bike on a 4x6' trailer. Such as this. Less Power said it will kill my car, but I don't know if he is being serious. So I need to figure it out. Someone want to explain GVWR and tongue weight? The car says maximum towing capacity is 1000 pounds and the tongue weight is 100 pounds. I assume tongue weight is something to do with the weight pressing down on the ball? So if I center the weight of the bike over the axle as best as possible, I'll reduce the tongue weight? Is there a nice and easy way to guessitmate the tongue weight? There will only be the bike, so about 500 pounds on the trailer.
