RV Storage compartments and measurements 1&2 from driver window going back to the rear wheels

Charlie:

Here are pictures of the storage units 1 and 2, starting from the driver's side window and going back. The first one is the propane tank. The second one holds the water box, which is 10x18 inches on the far right of the compartment. The propane unit measures 19x52". The next compartment (holding the water box) measures 12" tall, 20" deep and 50" wide. The hinges stick out 1 inch for that small portion.
