If you substitute 40-50% of your base malt with rye malt, you will see exactly what I mean. It is thick, syrupy, and oily, which will serve to counter any perception of dryness in your beers. Try it! Other experienced brewers will support me on this.
Rye is not the answer to problems with body. It's got a pretty powerful flavor, and at the % recommended above - you'd almost be making a Roggenbier. Carapils, Carafoam, or maltodextrin powder is the answer if you are looking at solving the problem with recipe tweaks.
I would double check your thermometers like others have mentioned, and also look at your process for determining your mash temp. Usually the mash will vary quite a bit from place to place. I found it helpful on the homebrew scale to stir and recirculate frequently, check temps in several places and average it out. If you can't get body by mashing as high as you say you are, then something else is going on. It could be a slight Brett infection or something.
