Yeah, as above. Just drain as much as you can. If it's clean, send it and forget it.
If it's looking a little dirty, drain and refill again in 1000 miles.
If you're worried about it, while the axles are out, it's easy enough to pull the third member and wipe as much oil out as possible.
Clean up mating surfaces really good before putting it back.
I'd say use a paper gasket here, I've had RTV fail, and bolts loosen up.
I think RTV stays kind of fluid even when fully set, I think this let's things move about a bit.
Others will swear by RTV.
