This method sucks but it works, I always keep a pre mixed muscle milk waiting for me at 4am usually double the dose to get a good 600 cals in with very little carbs and high protein.
My girlfriend gets pretty pissed when my alarm goes off at 4-5 in the morning but she'll live

On the contrary, I'm actually a hard gainer so to speak, not probably a true ectomorph, but maybe between that and a mesomorph. I try to do everything by the book, and I always ate a lot. Even when I was natural, my body will start losing size as soon as I decreased calories for just a week. My body seems to fight weight. I know this guy around my size that only takes in 3000 to 4000 calories a day guestimate, and he can maintain size and even get bigger. If I brought my cals that low, I'll be back to 230 to 240 easily.
Just a jab bro! I know how the classic ectomorph thing is cause thats what I am. I hate it. Your stats are extrordinary though. I am on your low end. I am around 235. Biggest Ive been. I can take a shit and lose 5 lbs. Miss one meal and the same will happen. I am sure you work your ass off bro. Like I said keep us posted.
