Putting a fridge in an RV is no fun. I just replaced the OEM 6cuft with a newer fridge same size. The old fridge came out onto the floor ok with a struggle sliding it partly onto a table chair first. Son and I. You need help.
Then the issue was getting the fridge out the door--too narrow. Door and door frame removed (big job))leaving a hole about 1/16" wider than the fridge seemed like. Might have been 1/8" really :) What a battle! Getting it down the steps to ground level was another issue involving the chair and some wood.
Luckily or else they make them that way, the OEM gas line was able to go on the new fridge's line, but if not, you need to adapt the LP connection.
The big thing is the very exact measurements. Watch out for the front frame on the fridge that sticks out the sides and the top. With the 1/16" to play with through the door hole, you can't angle it to get one side out and then rotate it through and out (or in for the new one) Of course the door hole was just wide enough higher up, but not enough lower down, so we had to lift the fridge up and out/in as part of the struggle.
Some on this forum have reported they had to get their fridges in and out of a window where the door wouldn't work for them. Yipes. Anyway, it isn't all that simple as it might seem. :(
