We installed four Lifeline GPL-6ct (6Vdc and 300 amp hours each wired serial and parallel for 12Vdc and 600 amp hours as a group) batteries in a custom box above the factory battery box. The factory box with a very modified lid became the home for the BrakeRite II SD electric/hydraulic pump for our disc brakes.
When Lew Farber thinks the new style Lifeline lithium ion batteries are ready for prime time, we will install them and greatly lower our existing tongue weight.
