Question:

Is a trailer made with a truck rear axle bad on gas?

My dad says that I should not buy this trailer because it would be unstable, and bad on gas. because its made out of a heavy duty rear truck axle. I trust his judgment (he used to be a mechanic), and spent a lot of time hauling trailers. He says that because of the rear diferensial, it would be unstable and bad on gas because it is pulling back on your vehicle.The guy that is selling it, on the other hand, says that it is not bad on gas and that it is not unstable. Although he is the one that is selling it. ;)How does this work?

Answer:

Trust what your dad is telling you. The gear ratio in a truck rear end, is a lot lower speed than one in a car.
There IS drag on the axle due to the gears but not much as there is no power to the axle, an economy axle out of a full size car is only marginally better a FWD axle is OK,NO drag. Balance is subject to the construction. When in doubt listen to your father
when is the last time your dad gave you bad advice/listen to your father he is right
