It seems that the industry is slowly moving away from wood stud, fiberglass insulation and aluminum siding to the fiberglass skin, aluminum tubing, solid foam for wall construction. Both have their p...

That roof looks like new !
3 or 4 times a year is a lot of work, but if all you do is a quick wash down and then spray, I'll bet you are done in under 1 hour !
Thanks, Yes it is work but the end results pay off if you plan to keep a camper a good long time. It takes me a little over an hour to do the roof and that is only because I keep after it. A roof never cleaned at 10 years will take over 3.5 hours to get it cleaned.
I have found that using 303 UV protectant on a clean roof 3 to 4 times a year makes a significant difference in reducing the roof and Dicor deterioration if the camper lives outside all the time. This can be reduced to 2 times a year if stored inside while not camping.
Since I have started helping friends repair their wet campers they just bought, (they never knew what they were getting...) I was totally shocked at the difference that the 303 and the cleaning did. I'm on my 4th wet camper repair now. The sun damage on a 10 year old roof that has never been cleaned or 303'ed has millions of spider cracks in the white layer, some very wide and all the way down to the black layer requiring a recoating. And they have very little white layer left. You can measure the white layer loss when you lift up the roof cap moldings. The Dicor is totally gone, dried up, split and crumbling in 10 years.
See this pic. This is 14 year old Dicor on my roof tank vents. The layer on top I added a long time ago. The bottom layer is original. These are the only 2 areas I have not E bonded.
The difference in life I feel comes from the 303 I use and the cleaning as Dicor has stated.
New roofing materials as your post started with, needs that extra level of UV protection. It is either part of the material itself or you have to add it after.
