New Blackstone Owner - Do I still need my grill?

I have a two burner griddle. I really like it, but I need more practice (or something) doing steaks. They don't seem to come out as well as on the BBQ. How do some of you cook them on the griddle.

I go out moose hunting for a good three weeks. With the griddle, I've quit taking the camp stove. I'd like to quit taking the BBQ also to save more room.
