Grounding batteries ?

[David@latitudezero]

I want to install solar on my cargo trailer; BUT it's 100% aluminum (yes, the frame too). How do I ground a house battery bank with an all aluminum trailer ?

Aluminum is actually a better conductor than steel.

You do no have to ground your battery to the trailer frame unless you are using the frame as the ground return.  It is OK to let the battery circuit 'float'.
