mm gearing help

[mach1stang]

hey guys, long story short i am going on vacation for 3 weeks on sunday, and my maxx is not done and my B4 is would not last too long in the mountains. so i am just going to buy a pede, i am going to buy one stock and bash it stock while i am on vacation so i dont go crazy, i am limited to supplies i can only afford the car and a stick pack for now, i also have a 7700 mm sitting on the shelf that i will either put in my carry bag in case or i will put in while i am still at the house bashing, but i was wondering if the mm 7700 would do any good with a stick pack in a pede and what gearing should i run in it?
