Thanks guys, Photo below shows the 37' with the drain hose hole.

Now, the 37' in the 2nd photo is yellow, both in this photo have the
spherical bulge on the lower/front end.
All 5 of my trucks came to me with no front sheet metal,
rusted sheet metal or sheet metal piled in the cab.
I have placed these against the frames of several and can't figure
out what that bulge is for.
