New roof! Should I use TPO or EPDM ??

Got all the old rubber roofing removed from the RV. Luan was soaked in several places. Really bad around the skylight area. Removed all the roof vents and the Skylight, Remove and moved the rear A/C up to the front area of the roof so I could start on the rear (don't want to have to take the a/c units off the roof because there very hard to handle). Striped all the Luan off the rear half of my RV. Replaced the Luan with 3/8 plywood using liquid nails and dry wall screws. Hardest place so fare is prying up all the staples that hold the strips of aluminum that make the curve that goes from the roof to the side walls of the RV.

Once I got the plywood screwed down in place on the rear section of the RV, I re-stapled the aluminum back on with an air powered horseshoe gun and moved the rear A/C back in place just to get it off of the way..
