If you have any recommendations from the manufacturer - follow them. This forum is not an ultimate source for everything, so the following is just my opinion:
Wash it with dishwasher liquid. No other treatment is needed for storage under roof. If you store it uncovered and there is a lot of sun in your area, you may spray it with 303 Aerospace after washing. You will find detailed instructions for EPDM roof on 303 website. It won't hurt spraying it again in summer, as 303 is getting washed off slowly with rain water.
I am not spraying it with anything, and when time will come, I will apply a coat of Liquid Rubber. The roof will degrade after 12-14 years no matter how hard you try. A 23ft trailer roof needs 4-5 cans of Liquid Rubber at total cost around $300. Over 14 years you would spend 2-3 times as much on spraying it with 303 few times a year.
My understanding is that white paint that manufacturers put on the roof, protects it from UV better than 303, and this paint stays on top of rubber for quite a long time.
