Just a note about the Andersen WDH. The 8" drop model is much heavier than the 4" drop model although the 8" is also much nicer for trucks since their receiver is higher. I had a 4" on my SUV and got Andersen to trade me for an 8" when I changed from SUV to Truck. I no longer use it since I went to a fifth wheel recently. As an FYI, when I packaged up the 8", the ball, the chains and everything in the smallest suitable box that I could, it weighed 62#.
Another FYI has to do with the silentness of the hitch, after about a year I noticed that my trailer's tongue coupler seemed a little noisy at times. After much research and talking to Andersen, they advised it's ok to use a greaseless dry lithium on the ball and coupler. I bought a can of "SLIP" off of Amazon and sprayed the ball and the coupler. SLIP goes on wet and after a few hours it creates a permanent smooth surface. Noise gone.
