Where do you find yearly RV sales, your #s don't match the RVIA data.

Valid point on wind drag, although I assume it works against larger motorhomes. When engine is sized for adequate acceleration and hill climbing, then it becomes too large to be optimized for fuel economy during level-road cruising. Additional overdrive gears help with that, but engines can only operate so slow before they become inefficient or create vibration problems, etc...
SSI: C’s Shine as ’16 Motorized Sales up 12.7% | RV Business
SSI: Class B Sales Roll to 13.1% Gain for 2016 | RV Business
Also show December sales versus previous year show Class B and C were up 7.1% and 3.6% respectively, while Class A sales were down 3%.
I'm curious what numbers you have in case these are off?
