The Rio Grande is only a few inches deep for several hundred miles and there would be no reason to pick out that area to cross with all those gringos watching from their RVs.
Go, enjoy the Big Bend NP. It's really a neat place to stay for a couple days to refresh after a long drive. You can wave at an occasional Mexican villager up on the hillside across the river where there's a small village. And hike up and down the river bank. Or even wade across in places. There's a wildlife marsh area there too (snakes!) with a wooden bridge crossing it.
We've been there at least three times over the years with zero problems. We spent 5 days there a few years ago. Not only is the Rio shallow it is actually dry in places. There is a slot canyon that the Rio runs thru down in the State park section that is bone dry. I suspect the river runs underground there.
For the most part the Mexican side looked very rough and inhospitable. I don't recall even seeing anyone on the other side. here is one place where you can get boated across at the eastern end of the river in the park but we haven't been down there.
