I ended up completely removing the mdf piece that made up the right side of the fridge cabinet/left side of the closet. It wasn't all that difficult to remove and proved much easier to trim on my workbench. The plywood piece to the left of the fridge I had to trim in place. In order to get nice straight lines, I used a 24" square that I placed on the floor and ran up the side of the generator box. Luckily the generator box was perfectly square to the floor on my chinook so this made easy work of the layout.
Once everything was trimmed to where I wanted it, I started working on new cabinet faces. I decided to use baltic birch, cabinet grade plywood. I love the light color, and the modern sleek look it has. Really solid, great stuff to build cabinets with too. I used the old closet face piece to trace the profile lines of the rear of the chinook. Took about 6 or 7 trips in and out of the chinook to get it just right, but it's just how I want it now.
I don't have a picture of it yet, but I also got the closet door cut, also out of baltic birch. It is absolutely amazing how much roomier walking into the chinook feels without the fridge sticking out so far. Speaking of the fridge, I am not going to put the fridge back here. This space will now be a stack of drawers with either shelves or a cabinet space up top. The stock fridge is way too big for me, and even in my house I never use the freezer.
Next thing I did was jump over to the stove area. I removed the stove and cabinet and got to work on making something new. I removed the lounge chair next to the stove, removed the cabinet it sits on, and build a new base cabinet that sits directly on top of the wheel well. On top of this cabinet, I will place my new fridge. For my fridge, I will be using a 3.5 cubic foot chest freezer with an external Johnson controls thermometer to turn it into a refrigerator. This is more space than I will ever need and since I am a solo traveler, I don't need two lounge chairs.

You can also see where I temporarily mocked up the counter top for the oven. Both the sink cabinet and the stove cabinet sit WAY too low for me. I don't like having to bend over to use these appliances. The freezer/fridge I will be using is 32 inches tall. Sitting on top of a 6" base cabinet, this puts the top of the fridge at 38". I will be making a new cabinet for the stove to match this height. This is a much more comfortable height for me. I can stand straight up and use them. In the picture you see, the counter top is at 42", so it is slightly higher than it will end up when completed.
You may be thinking to yourself "why would you put your fridge right in front of the window? Isn't it going to cover up some of the window?" The answer is yes. And when I move over to the other side and raise the kitchen sink cabinet up, it will DEFINITELY cover quite a bit of the window. This is a non issue for me. I am eventually, probably early next year, going to go the route that willywalderbeast went. I will be removing the windows, fiberglass the openings, and install arctic tern windows. These windows will be more forward than the stock ones and my cabinets will no longer interfere with the windows. I am not a fan of the stock windows at all.
I don't actually have my fridge yet, so I will be waiting until then to build my stove cabinet to make sure I can flush everything out perfectly. Since I've hit a temporary dead end for now, I jumped up top and started working on a new overhead cabinet where the microwave used to be. Again, even in my house I have never used the microwave so I just decided to scrap this as well. I started building a new cabinet to match the angled cabinets above the dinette. The 3/4 plywood is a little thicker than the mdf, so the faces don't plane out very well. This is no big deal to me because eventually I will be replacing the slanted mdf cabinet faces with baltic birch plywood as well.

This is where I quit for the day. Overall, for about 12 hours of work, I am happy with the progress I've made. Next step will be to cut down, reflare, and cap the propane line for the fridge. Then I will build the cabinet for the stove and finish out the overhead cabinet. I will have to extend the propane line for the stove so it reaches the new height of the stove. After that I will finish facing out the old fridge cabinet and start building drawers. Once that is done I will finish installing my lifeproof vinyl flooring. I'll make sure to keep the pictures coming.
