Truck camper Clear Coat, can this be restored?

I am doing the same thing with my new to me 2002 Lance 1130, Its pretty dull and faded. I got one side just about done, but its really something I do not like doing any more.
When I was younger I could hang on to a polisher for a lot longer time than I can these days.
It is coming along slow but sure, eventually I will get the whole thing polished up.
