Cross brace missing?

[swamp rat]

I have a question, i have looked at a number of builds here and all that i have seen there was a cross member both foward and behind a rear frame tank install, i just went out and took some pics, i have 1 rear frame cross member (brace) about 12" from the rear of the frame and nothing else until about 2' from the front of the bed, am i missing a cross member?

The 3 pic's go from the rear of the frame looking at the passenger side

Disregard the squair tubing as that is part of my current hitch and will be removed for a reciver type later.

Thanks.
