Hmm. Meyers Briggs personality types have some interesting groupings for what types of jobs they are more prevalent in.
Some people have even harder time shutting off internal mental chatter. So, I would suggest spending a bit more time with daily meditation. Also cutting caffeine way down. The RVing how-to videos have some (later more recent ones) which take you through meditation prep for before RV sessions.
Trying to set up distraction-free environment can be really hard.
If you think you do not have time. Then remember that often times after taking a break from working on a problem, when we come back to it, the answer will just pop out (subconscious working on it). Schedule a meditation break for yourself. Even if only every other day to start.
INTP and INTJ probably spending more time analyzing how RV works than on meditation. Try it, and do not think of it as a "waste of time."
