I've had to hard brake a few times in my Axis. Wow! I couldn't believe how well it stopped--well short of where I thought it would. (In none of those instances was I pulling anything, nor were they on the freeway.)
My F-Series were the same way (granted they are designed to pull a lot and thus will have oversized brakes).
Not using this as an excuse to go faster, just giving my experience with the E-Series chassis Axis. I'm sure the F-53 based campers are different beasts alltogether.
Usually, though, well go 70 or below for most of the trip as it does get noticeably noisier above 70.
