Thanks all, did it last week. Used the Proflex primer and then Liquid Roof.
Lessons learned:
-Prepping. I removed any old or cracked Dicor caulking and re caulked. I left the AC units in place. I have Eternabond tape at the front and rear caps.
Power wash, and scrub it with dish soap. Let dry. REMOVE ALL SILICONE BASED CAULKING!
-The Proflex primer is an epoxy based primer. It comes in a 2 gallon set. 1 gallon looks like white paint, the other looks like clear epoxy. You will mix them together. Mix a quart together first to do your brushing. Cut in on the sides and around the vents, ladder, AC unit, etc. Go right over the Dicor caulking and onto or over your Eternabond tape if you have it. You shouldn't have a problem with sagging because it doesn't need to go on that thick. Then mix up the rest and roll the roof. The primer is easy to apply and really heavy duty. Thickness is not important with the primer. I had plenty for my 34' Bounder.
It was 65 degrees during the day and 38 at night so it took longer to dry than normal.
IMPORTANT! = Obviously you have to wait until the primer is dry enough to walk on.
The key is dry but still tacky. This wil be weather dependent. It could be 24 hrs or like mine, 4 days. DO NOT LET THE PRIMER COMPLETELY CURE, it has to be tacky. (Per the manufacturer. I called them and asked.)
-Now the liquid Roof. The replies on this topic on the amount needed are interesting. Mr Wizard says 25 gallons. That is insane. I bought 5 gallons and made it work but 6 would have been better. Use the calculator on the website and add 1 more gallon.
Thicker is better.
They say once you mix it the pot life is 3 to 4 hrs. That is true but as time goes by it gets thicker and harder to work with. So mix 1 gallon 1st to do your cut in on the sides and vents etc. I went under the AC units as far as I could. Use a brush. It self levels really well. Mask off your ladder, bumper, and put a tarp down in case you get it on your shoes. Wear latex gloves. It cleans up easily with mineral spirits. It will sag on the sides so be careful and mask it with painters tape. After cutting in, mix up the rest. You will need a squeegee and a roller. Pour some on the roof and squeegee it out. Then lightly roll it even. Work front to back ending at the ladder. Take the masking tape off as soon as possible, but not too soon because of possible sagging. I waited until I was completely done and had to use a razor blade. It took 24 hrs to skin over and I waited a week to walk on it. It looks great and feels like rubber because it is!
I hope this helps anyone looking to do the same with their roof. I know I had a lot of questions before I did it.

I brushed mine on, but I only did the seams and protrusions on my 30-foot Allegro. It has an old-school aluminum roof so I didn't need to do the whole thing. I used less than a gallon.
The warmer it is outside while you're applying the quicker it thickens. It is thick enough not to run if you're careful. I applied mine with a cheap paintbrush. I didn't have to tape anything off - it's thick enough to stay where you brush it on.
I didn't use their primer. I wire-brushed the loose stuff off and washed it with soap and water (Dawn to be specific).
It's been a year now and it's still stuck like glue, really flexible and doing is job. Really good stuff.
