LATES UPDATES from the OP
I have the 3 X 120W panels installed. Somewhat flat mounted longwise with the length of the MH. The panel inside towards the roof centerline is raised with 6" uprights plus the slight curve of the roof. I see two problems, first is I have not had any good sun. But today with the overcast and some sun, by time I got the third panel up and running. I did manage to get 35Ah charge in the batteries with the time the three panels were on line . I am happy with that for now. My second problem looks like the trees on the north side and east side of the HM may put just a little shadowing on the panels. I can live with this for now. My main solar objective is for when I am away from home. Even with 35Ah that should keep the batteries charge when sitting at home with out the converter running.
I will wait a few day and give further updates. Gary
