I have an older mobile home and my tenant in there said that when the tub drains, bubbles come up in the toilet bowl. He said there's no trap under the toilet. Is there supposed to be one?

No, there is not supposed to be a trap under the toilet. In fact, such a trap would be prohibited. The trap is the toilet bowl itself.

Sounds like maybe you have a venting problem.
