Most of our camping is boon docking or camping in National Forest or State campgrounds with no hookups.The first photo shows the water pump I installed so I didn't need to hold the water jug until it gravity drains into our FW tank.
The under the seat storage W/drawer was a problem because there was nothing to keep the things stored there from pushing out the drawer while traveling. I did a down and dirty fix with existing plywood but it works.
After going over gravel/dirt roads the speaker above the sink pulled the screws holding it and fell down on the counter. The reason is because the speaker is taller than the space it was fitted into so I made a spacer and reinstalled it, hopefully it will stay put now.
