I have a Tahoe Q4 and was wondering if you guys just screw your battery tray or box to the hull or can i just use a healthy amount of 3m 5200 and glue it down?
I always screw the tray down. Just make sure there is nothing below the screw. ie: hose, wires, fuel tank, etc.
I assume you are screwing it to a deck and not the boat hull!
If your battery tray was at the same angle as the hull, it would probably be screwed into a piece of wood glassed to the hull (Tracker would probably do this...). If it was horizontal, it is screwed to a shelf glassed to the hull...
