X2 doors come off easy, made to be reversible,
just take the doors off
anybody with 'any' mechanical ability, can remove screws and remove a window and put it back
it doesn't take a $1000 service job to take out a window and lift a fridge in
assuming your not talking about a french door fridge with a bottom freezer and 30cuft of storage
i took out a Norcold and but in an Avanti 7.5 cuft residential fridge
with one friend helping me do the lifting,
out and in, through the front 'bus style' door, and i'm a little guy and he was just avg, at the time i was 62 and he was 59, i'll be 70 next month, and could still do it if i had too,
i did all the wiring and prep work myself
did not need to remove the dining room window
although i would have,
i have removed and resealed windows in other Rv's
