Do you really want to go thru the headache of getting the spare tire compartment open and climbing in there to service the batteries on a regular basis?Do you really want the highly-explosive hydrogen fumes out-gassed by the batteries while they're charging directly under your feet? Or mama's feet for that matter?Do you really want the highly-corrosive electrolyte vapor eating away at the front end sheetmetal and control components located in the spare tire compartment?Have you thought about how the additional weight of the batteries ahead of the front axle might affect both steering and tire life, as opposed to balancing the weight between the front and drive axles?No answers. . . just questions for you to think about.FWIW&HTH. . .
