I also do that: simply close the black tank and let the flusher fill the tank. There really is no danger of "overpressuring" the black tank since its vented to the roof. Once its about 1/2 full I just open up the black tank valve again.

Do you have any data on MPG versus speed for your Axis under similar conditions?

Given that we're pushing a brick I would agree with that: slowing down would significantly increase mpg. I haven't really done any speed vs mpg measurements. Most of our travels are 65-70 mph (when we aren't in a hurry I'll go 65, when we are I'll go 70). My last two trips were at 65 on the cruise, Tow/Haul off and pulling the Escape (one of which I got my high of 9 mpg). Our last drive was from MI to DC over the hills of PA and thus we got a low of 7.5 mpg at one point (also with Tow/Haul off).
This weekend I'll be reversing that trip (DC back to MI) and thus I'm expecting similar mpg (7 mpg in PA, and 8+ in OH & MI).
