You don't need to drop the TT to get separate weights on the TV and TT. Before I drive onto the scale, I take the WD bars off. Then pull the TV onto the scale so that the TT's front jack is off of the scale. Jack the TT up until it just clears the ball, then TV is all alone. Drop the TT back onto the ball, pull forward until the TV is off of the scale, but so that the TT's jack is still on the scale. Do the same thing lifting the TT off of the ball, then you get TT weight only. I've done this for years with great success. Other places to find weigh stations are recycling centers as they weight trucks before and after they dump. Some are free.
