I have a 2008 189FBR (no slide) which hubs and I are living in full-time. I have totally remodeled ours, you can see the projects here
, don't know if any are of interest to you. I am a 65 year old woman who does all the work (hubby has no interest) so don't be overwhelmed - you can DO THIS!
If you don't plan to camp often without electric service, you can replace your refrigerator with a regular dorm size (or larger) refrigerator for a lot less money than an rv refrigerator. That's what my sister did.
Good luck, and don't sweat it
