LED strip lights are usually arranged in numerous parallel segments each composed of a few series LEDs, thats why you can cut them to length. Joining strips together should not be a problem as long as you have the current available to drive it. Due to the way they tend to be used in an RV (simply attached directly to the 12V), you should have the current to drive them.
Our fresh water fill valve has developed a small leak through the electrically-operated portion. The water pump cycles briefly and repeatedly unless we close the manual side of the fill valve.

Our bay door gaskets were getting pretty tired. I had a few with small cuts in them from loading and unloading. In some areas it had started to slip off the edge of the flange, especially on the bottom edge where it is easy to lean on them when reaching inside the bay. They had also become more stiff over time which increased the force needed to close the bay doors.
