First off here is link on How To Marinate a Steak. 

And a video linking to tips on buying a great steak.

At the start of camping season I put my “dinner serving” amounts of steak in a zip lock with the selected marinate and toss it in the fridge over night (label the marinate so you know the flavor you are cooking). The next day I freeze it so when we go camping it is ready. I move it into the RV freezer and it is there for whatever meal you have planned. Cuts down on the ingredients you need in the RV and the mess of marinating raw meat in the trailer.
