I can't believe that your numbers are correct. 5%? I suggest Marketing get out and examine that number again.
I was looking for the most equipped factory built toy hauler on the market. I'm sure everyone else buying one is too.
That was Cyclone at the time. I'd have gladly paid for auto leveling, hydraulic front jacks, remote control jack and lighting system, backup camera, and tire pressure monitoring system if they'd have been an option.
How many people paid extra for the outside security monitor? I'm guessing not many, but it was still an option.
I hear what you're saying...these things are available in aftermarket, but that's buying things twice. If we extrapolate that idea to the entire coach, a custom rig would be in order.
