The Class lV or V hitches we have that are available for your 2003 Newmar Dutch Star RV require welding installations.
I recommend the Curt Class V Universal Weld-on Hitch, part # 15901. This will fit frames from 18 up to 44 inches, and with the side brackets produces a drop of 3 inches from the frame. This hitch has a 2 inch receiver opening.
You will want to make sure you do not exceed the towing capacity of the RV. view full answer...
Custom fit roof racks for a 2004 Chevy Malibu Classic are going to run higher than your current budget but there is another option.

I do recommend going with a custom fit rack, see link, if at all possible. You will get the best fit and performance. view full answer...
