New floor

This weekend was really busy for me, it was on the cold side and windy so I wasn't in any rush to do any outside work on the RV so I changed gears and worked on my 3D printer. I did clean the inside of the RV for a bit and tested the seating for a few minutes.
I have to do a search for a possible nest of hornets. I keep finding the suckers in between the windows and under the cushions. I think there may be a nest in either the walls or the roof. I will find them one way or another when the weather warms up.
On Sunday the weather warmed up quite a bit and I was motivated. First thing in the morning I went to my favorite home building center and bought some supplies for the day. My goal was to patch the floor in the bathroom, fix the water tank hatch and cover the large hole left by the water heater.
The floor patch was strait forward and simple and only took me an hour to do. I opted to remove all the damaged wood and cover the remainder with new half inch ply.
The hole where the water heater previously lived was where I got a little creative. I have not had any luck with finding replacement siding for the rig so I figured I would keep the hole and use it as an access to the vanity plumbing. Now all I needed was a cover. The water heater was no good so I cut off the hatch and replaced it where it once was. It was a perfect fit of course.
The water tank hatch which is below the water heater access panel was in need of serious repair. Whoever fixed it before me did a complete hack job. I had to cut a new piece of MDF to the correct dimensions and fit the old molding to it, which is so bad that none of the corners connect. I also installed a new lock because there was none.
I was also playing with the idea of mounting the water pump in the water heater hatch along with a filter.
That is still in the works.
