I can see three things at minimum going on, on your roof. 1. You’ve got a couple visible tears. 2. The dicor looks pretty minimal and pretty old. 3. You are starting to get some dark areas that look to be UV damage to the rubber allowing the membrane to start showing through (gray splotches).
Those rips obviously need to be patched, but you should also probably refresh your dicor and look at doing a recoat. We put new dicor and recoated the rubber roof on our previous motorhome for about $350 and a day of diy work. The roof looked like new.
Just because you don’t have any visible leaks inside does not mean your roof is not leaking. Sometimes there can be extensive rot even without staining on the inside. It’s great that you are being proactive.

Clean and recoat. If you can’t afford to have the roof recoated, Dicor (self-leveling and non-sag) and Eternabond tape are the answer until you can.
Looks good for 20 years.. check seals.. seal where needed.. leak test what you can see inside
I’d say a good wash with rubber roof cleaner and conditioner, then inspect all your seams around vents , ac, antenna and the edges.
Fun fact the black streaks down the side of the camper is usually from the roof

I have a 2002 Sunny Brook. No leaks coming from the roof, but I want to make sure everything is in good shape before the summer.
