Rving In Mexico and South America? Where Did It Go?

We have been snowbirding in Florida and Georgia. I had dreamt of wintering in Mexico, but I don't know where. The campgrounds near Brownsville, Texas promote that they are warm like Florida. I don't know if there is that much to do in the Rio Grande Valley. We like canoeing and birding. 

It took me two months to figure out that my RV. net login is obsolete. My Good Sam Club membership got me into here.
