I did the same project on my '99
Scamp a while back. I had some difficulty removing two of the screws from the cabinets. I was completely removing all the hardware and replacing, as mine was mismatched. See this tread:

Once I got the impact driver, the rest of the project was a breeze. I did have to add a couple of washers to the back side of each of the cabinet door pulls as the included screws were too long and would not tighten fully. Not a problem, could have been more patient in finding shorter screws, but the washers work fine.
I got the impact driver and all the new hardware at Menard's.
I have made two trips from Mich to Florida and many short trips since replacing them, and not one screw has come loose. None of the doors sag, and the new hinges keep them closed better.
When
painting the doors, make sure to use a decent primer prior to
painting. Most
paint will not stick to the finished surface of the factory doors without it. I have had zero chipping or peeling of the
paint - VERY satisfied with the results.
With regard to your trailer being a '15 vs older, I doubt it would make any difference. They have used the same way of constructing the cabinets for decades. Perhaps the finish on the cabinet doors is slightly different, but I would assume they can still be painted with a little care.
