Well, I dont think much would be gained since most of the leaks come from vents and AC which if you put bed liner around them, you would never be able to replace them. The AC has a gasket and no caulking. I personally would like to see TT companies have a one piece alum roof with molded lips for vents and AC where water cant in.
Me, I will just stick to the regular stuff. When it needs to be replaced, I will just do it myself.

Wisdom is the right use of knowledge. To know is not to be wise. Many men know much, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.
Had front of my Komfort shot with Rhino a few months ago. Even sprayed the propane tank cover. Very happy with results. Easy to clean and paint color matches. I went with the coating instead of "diamond plate" because it matches better with my high gloss gell coat. It has protected well, against stray rocks kicked up by my dually. Roof application should work fine in my opinion.
There is a Rhino dealer in Columbus, Ohio that does it. They have a picture of one of the MH they did. They are sending me a quote for a 30' TT but I'm a long way from taking that jump. Rhino linings have been around for years and you would think it would be a real buzz if it was that good and cost effective. I think the $$$ will be the show stopper. JMHO

I asked my a local truck and stuff type dealer about his spray on Rhino material on a large 8" x 20'-30'+ RVs roof. He gave me this deer in the headlight stare and made several comments. His first comment was why would anyone want to add that much more weight to the RVs roof. His second comment was "your kiddin' right".
Did he say how much actual weight the Rhino material would add?
Many vehicles are coated with Rino Liner, and it is not that heavy.
I have heard of Line -X used as a coating too.
I was quoted about $4,000 to clean my roof, coat it with Rino liner, and I did not like that price, I have a 30' Bounder. I guess they price it like a pickup bed, so much per square foot, and there is a lot more than 2 pickup bed's worth of square footage up there!
I coated mine with 4 gallons of Herculiner bedliner, it is white. Each container is about 8 or 9 pounds and my guess is over 1/2 the weight will evaporate as the product cures. Some of the Zyelene soaks into the EPDM, and the chemical smell does get inside the RV, so ventilate it well, and don't plan on taking a trip the next weekend, though I lived in my RV the night that I coated the roof, with the windows open.
The Herculiner is very flexible, I used a old coffee cup to dip out cups of the stuff and pour onto the roof. When done, the coffee cup was coated with about 1/8" thick coating of herculiner, and I was able to remove it in one piece, still have it, never took a picture of it yet. The stuff can tear, but I was able to get it off without tearing it up much. Yes it is still flexible 1 year later.
If you look in DIY, you can find my post about the bedliner on the roof, with pictures.
