Truvativ cranks
I have a set of Truvativ Rouler cranks on a bike I bought.
The cranks are 53/39 and are made of aluminum.
I am experiencing a problem that others have mentioned, but I have not found a solution.
The non-drive side crank will not stay tight. I have tried using the correct torque, really cranking down on the bolt, and even loc-tite. Nothing keeps the crank arm tightened properly.
Has anybody come up with a solution or will I really need to get another crank?

What you need to do is to have the BB shell faced. This is a known issue and the 2 outer surfaces of the BB shell NEED to be precisely parallel with each other otherwise there will be problems as you have described.
I think this is an issue with all outboard bearing designs but the Truvativ BB design is known to be particularly sensitive to it.
