After yet another week of painstaking mechanical problems and another blown differential, we're ditching the Dolphin. We bought our old girl because she was built upon nothing but a Toyota pickup. With this knowledge we knew as long as there were never any problems with the rear differential, the only part not shared in common with an average Toyota pickup, we’d be able to fix her with ease. But, Murphy’s Law struck and we are simply incapable of buying the parts necessary to fix the Dolphin in this country.
