Welcome to iRV2.
There are many posts on residential fridge installs.
Posting your existing fridge's model number and even a picture of it's location , showing the cabinets around it, along with measurements will get you a bunch of ideas. I've been involved with three change overs myself 2 / 2 door and one 4 door replacement.
Info on posting pictures is in the " FAQ " drop box in the blue bar , under your welcome message.
Edit : If a two door apartment style will fit they run , $400 on sale , larger french door counter depth about $1200.
