i recently removed our rv fridge and installed a new rr. our rr is sitting on an elevated cabinet about 1 ft above the floor too. based on your description, i wonder if you have an access door from outside. if so, most likely you can work things out from outside without moving the fridge. on mine, it's doable. however, if you really need to pull it, make a workbench/platform at the same level as the cabinet floor at (at the time, i found a used table pretty ugly
for $5 on craigslist and i cut the legs shorter to make it in perfect height). look for the fastening screws/bolts from rear, front sides and top edges. once you loose up the screws/bolts, the rest should be easy.
