I've done two of my rv roofs with Henry. Previous fiver with 287 and it held up great even in the Phx area for 5 yrs before I sold it. Best things... It stayed very white, had texture-not so slippery, and NO more streaks on the sides.
I did my current fiver last year with 587. It's more reflective than 287 and I can tell the difference, big time! We've camped in hot areas this year, set the t stat on 77 and the one 15k AC cools to set point very easily and it cycles nicely. I also sealed the AC return plenum and wrapped it with FG last year but I think the Henry 587 made the most improvement.
I pressure washed the loose stuff off the rubber, hand scrubbed with scotch brite pad/tsp solution for a great prep for the coating w/o needing any primer. Then fixed all caulk with dicor NON leveling and seams with eterna bond and then two heavy coats of 587. The Henry 887 is all silicone and even more reflective so it's probably worth the extra bucks.

I'll take a recoated roof over the original chalky rubber any day, any time!
Home Depot had the 587 for $89 for the 5gal. However somebody asked in their questions section about using it and the Henry rep answered that he recommended Henry 887 for wet areas.
Now maybe I'm thinking of using the 887.
