Two weeks on our own so far, husband and wife team.

Was this you at the end of the six months?

 

In my 8 weeks of training I don't remember sleeping more than 2 hours in a rolling, bumping, bouncing sleeper no matter how tired I got. I too thought I'll eventually get so tired I will sleep. No matter how dog tired I got, and I never got more tired in my life than during those 8 weeks, I would get 10-30 minutes, get bounced awake, take 30+ minutes to fall back asleep, sleep until the next big pothole crash, wash rinse repeat. I never doubted my trainer's ability so the only reason I could not sleep was the being shaken awake or getting angry that I couldn't sleep.

I don't know of any way to know in advance before trying to sleep in a moving truck. Obviously if someone can fall asleep at a rock concert or you haven't once in your life had a neighbor quiet enough so you could sleep next door I'd say that will likely carry over into the truck. It could be a matter of adapting to the moving truck or it might be a permanent feature of someone.

Check where your fifth wheel is at. In my cascadia, if it's all the way forward the ride is very harsh, at least it feels like behind the wheel. Definitely a noticeable difference when it's slid to be at center of drive axles
