aerodynamics
Would the Forest River Flagstaff Micro Lite 21 FBRS be considered to have good, fair or poor aerodynamics?

If you can improve mileage by 1 mph - that's a 12.5 to 10 % increase for most folks.
Truckers would kill for 10%.
Some very scientific studies have been done on automobile windshield shape. 30 degree slope reduces resistance on the windshield about 25%. The winds shield still have to move all of air pressure out of the way at that speed.
The way we tow, and the speeds we drive have a greater impact. Changing your cruise speed from 70 to 62 will normally gain you more mileage increase than aerodynamics. It takes approx. 27% more power to go 70 mph than 60 mph because of the resistance of the air being moved out of the way.
Weight does have an impact - very small unless you are in mountains with a lot of uphill driving.
Smarter driving is the best thing most of us can do to improve fuel mileage.
