Frontal Area
I am brand new to RVing, and want to be safe and comfortable.I have a 2018 Nissan Frontier Crew Cab 2wD. Max towing Capacity is 6300lbs Tongue Load 630lbs. Max GCWR 11,250lbs. I found expandables well...

I've always seen frontal area as the WHOLE area going forward. If pulling a trailer 8 'w, by 10' tall, you have 80 square ft. Even if the tow rig takes up a 7x7 or 49 square ft.
Then one need to factor in aerodynamics of the rig. How smooth, rough, flat fronted etc the rig is as to.How much HP one mat need to move a given rig down the road. This factor can vary HP needs by plus minus 30% from ave.
For most of us with RVs, we are better off mpg, lesser HP needs with a slightly heavier fiberglass walled trailer vs a lighter aluminum corrugated side trailer. The extra Wight does not strain your rig as much as additional wind resistance as aluminum siding adds.
