I use to have a 30 amp motor home. Under "just the right conditions" you could run both AC's, but that was rare, you certainly couldn't count on it. I did some research and found a box to install that allowed both AC's to run. I can't remember the name, but do some searching and I'm sure you'll find it. If I remember right the generator is wired like a 50 amp service so there's separate legs to each AC, and you split off one of those lines into this box and then plug into two separate outlets. I believe that's how it was, like I said can't remember, but it did work, and was somewhat easy to install.
