Sorry for the late response. I'd say it was more exhausting because Hwy 1 has a lot of constant curves, punctuated by some pretty sharp turns on hills coming up to fast inclines, so you're essentially carving into some pretty fast decelerations and then accelerating out of some hairpin turns. This would be difficult even in a smaller sports car. The long travel doesn't dramatically affect things, but you tend to carve in maybe a little more intensely and you have to manage your speeds.
It says 55mph on the roads but some of them are so windy you'd be hard pressed to do 40mph on a good day, and it was dumping rain.
I will say, and a lot of folks might gloss over this, but the upkeep on the long travel components is a lot more intense. For example I got home friday, and yesterday I took the car to the self serve car wash, and blasted it with soap and sprayed it off.
Later in the day I started getting a truly dreadful squeaking noise. Like "oh sweet baby jesus" level bad as I was on the streets. So bad people looked at me like i was driving an 1980's level shitbox corolloa level bad. Basically I think the soap dried out the uniball polyurethane bushings. So today I went over to REI and bought some Triflow spray on dry lube (it's basically graphite powder in a fish oil medium) and sprayed the uniballs on the UCAs, LCAs, trailing arms, and pan arm bar, and it totally went away. I was also advised to hit the bushings too, since it won't affect the existing grease.
Basically, if you daily drive a long travel truck, prepare for a lot more time spent under your truck.
