Yes, the 1-1/2 inch line is the gray water line. Is it the drain valve itself that broke? Or is it part of the pipe that connects to the tank, or between the tank and the valve?

If the valve itself is broken, it is simple to replace. The valve actually consists of three parts - two end pieces that are glued to the pipe, and a slide gate that is bolted between the end pieces.

Note that it is common for the drain valves for the 3" sewer line and the 1-1/2 inch gray water line to be combined in one assembly. Take a look at etrailer.com and put something like "waste drain valve" in the search box. Lotsa pictures, and semi-reasonable prices. The attached picture (below) shows an example, but there are a dozen different configurations. You will need to figure out what you have, and replace it.
