Be very careful with the power supplies for motor homes and trailers. My friends have had very bad luck with them. Basically they are power supplies for the vehicle and the high amp range is for the utilities within. 10 amps is more than sufficient to keep a battery bank up and running. However, if you draw 10 amps continuously from the load you may need to do something else. That is a lot of continuous power. I have put up a system that draws more than 10 amps intermittently and the battery acts as a large capacitor. Of course, that has only been for 8 years. ;-)
