Basically I was thinking about putting Line-X white on the roof so that it is leak proof, scratch and dent resistant, and UV protected for life. Has anyone else done something like this?

Welcome to the forum.
I had a Dicor rubber roof on my previous TT which I purchased new in 1999. It served us well with no issues until we traded it in just a month ago. I never coated it with anything, but I did get a tube of their self-leveling caulk a couple of years ago and coated some of the existing caulk that had begun to form cracks. (That is normal over time and is their recommended procedure for maintenance.) Other than that, it got washed several times a year.
I probably should have used some 303 Protectant on it but didn't. Those that do so regularly report slower aging of the roof material.
If this is your first rubber roof, I think you should follow the manufacturer's instructions for a season or two and then see if you still think you need to coat it. There are tens of thousands of these roofs already in service, some for more than a dozen years now. There are really only a couple of real issues with them:
* Tears and holes from external sources like tree limbs. No additional coating will prevent this.
* Cracks in the caulk on the seams. This is normal over time, and simply needs routine maintenance. Coating the seams with self-leveling caulk is the recommended maintenance. I prefer Dicor products, but others have had good luck with other products including the Line-X. As long as the product is manufactured for rubber membrane roofs, it should work well.
Like most items on your RV, the roof needs to be inspected periodically. Coating the roof denies you the opportunity to see what is happening to the membrane itself.
