My theory is that Dipper's real name is Max. Here are my reasons:

1) Alex Hirsch said his name shares something with Mabel's, which I agree is probably the first letter.

2) Dipper and Mabel are based on Alex and his sister Ariel (which also supports the first letter theory, since Alex and Ariel both start with "A").

3) Mabel's name ends the same way Ariel's does (MabEL, AriEL), so it would make sense for Dipper's name to end the same as Alex's. Max is the only (common) name I know of that starts with an "M" and ends with an "X".

I think my theory's pretty solid. In fact, if his name isn't Max, I will be surprised.
