That's true. I weighed mine before the instal and everything weighed 164lbs. Considering the only thing I lost in weight was the spare at 73lbs i have a net gain of only 91lbs. I will be putting my spare under the trailer (truck used 95% to pull it) i will gain some of the 73lbs back but not much. Planning on putting spare just forward of axles. Biggest drawback I see is moving the spare. If i could find a large enough and skinny enough tire as a spare I will stuff it back where it goes. Only thing stopping it is the width of tire.
