I put LED strips in all the Fl fixtures in the Safari dp, they never did burn out, and are still working for the current owner, 6 years of use maybe more
And yes I got them from Amazon, 5 meter roll of 5050 SMD LEDs was $12 when I did it those are warm white, these led fixtures I'm using now, are daylight bright and I really like them, the trouble with the waterproof covered one's is they do run hotter, because of being sealed up, they are supposed to be outside in the weather,
So closed up in a light fixture inside the RV, they will be hotter, I experimented with some, then gave the roll to somebody to use outside
The clear covering also does a little bit of diffusing, but I prefer the bare stripe with OEM fixture diffuser cover,
For outside expose weather conditions, the waterproof encapsulated strip should last longer, but we are discussing inside use here
To the OP nice job looks good, good luck,
I would not worry about converter charging village,
My experience is it will not have much If any effect on the leds,
Heat is really the determining factor in deterioration and failure
