There is very little overlap in the two groups functionally, so good to join both. BHA is working at the policy level on issues that really matter to the public land hunter/angler. RMEF has a huge and broad membership (which is great for generating funds), and they tend to focus on on-the-ground habitat and access projects and tend to steer clear of the political hot potatoes. I've worked with both groups and they're definitely doing good things for all our benefit.
