I don’t think there’s one for overlanding. I purchased a set of USFS National Forest maps for all the major forests in my region. Those have been extremely valuable for supplemental planning via Gaia. The maps are really hard to find, though, as they have not been in print for several years.
There is a web site with reviews and videos on various trails. I’ll probably think of the name once I click post. I recall that it wasn’t very complete for the SE.
