Aerodynamics Matter !!
Hello All. First post here... wanted to share some data on aerodynamics. I am designing an ultralight (under 100 lbs/ft) small travel trailer and wanted to find out the effect of shape on aerodyna...

One (of the many) things that annoy me about the RV industry is the way they ignore basics of aerodynamics that could be simply accomplished for minimal cost. Look at all modern cars/trucks, they have become very slippery in design. The headlamps, mirrors, and even door handles have been designed to reduce drag. Now look at the typical RV with multiple A/C units, vents, antennas, baggage doors, and windows all sticking out in the air stream.
Much could be gained at minimal cost by smoothing the body and components. Why can't those A/C units be mounted inside or underneath where they would be out of the flow? Why are all the other things just added to the surface with no consideration?
Most of what the RV manufacturers have done regarding aerodynamics is for marketing purposes, not real gains on the highway.
