So how to measure frontal area of trailer?
I found post from airstream forum:
Hey there, I have a flex and will soon be an Airstream owner. I've been doing a ton of research on this issue. The good news, according to Ford, if you are within your weight limit and using the class III set up they recommend it's doable. The frontal area question really worried me since there are conflicting details on the net about how to calculate. So, I called Ford today, and after about three tranfers I got to the right person. I wanted to know what does Ford mean when they mention the 35sq ft limit for frontal area. They said it is the height of the object being towed that is greater than the tow vehicle. The model Airstream I plan to purchase is a 1960s 26ft overlander that specs at about 3200lbs. The width of the flex is the same as this older model, 88 inches. The flex is 68 inches tall and the overlander is 107 inches tall. The height difference is 39 inches. I used a sq footage calculator, and it comes out around 23 or 26sq ft. Can't remember the exact end number, but I did it over the phone with Ford, and it was well under the limit. I'm feeling pretty optimistic about my plan. Ford also noted that a trailer that's curved is even better! Good luck with your research.
