Hi Techs, a guy on rvnet added an in bed aux fueltank to his dodge.... it is a gravity feed system..quite simple....can the chevy duramax handle this same setup..was a rds tank box combo...the simplicity of installation and utilization is appealing.
thanks for checkin this out..bc

I believe gravity feed to be illegal in most states, unless it is shut off while driving. In any event, it would work out the same as the dodge.
