This is normal if you are within the turbulent air zone. Increase your
following distance, as an added benefit you will be able to dodge road
debris they kick up, not to mention windshield-damaging rocks.

Also normal. I live in an area with strong winds and frequently come in
from a trip with one arm more tired than the other. Unless you are saying
it pulls left with the wind coming from the left?

As for the rest of it, it is very likely you have some issues that need
tending. But even with everything as it should be, you are driving a
vehicle shaped like a box kite that reacts to wind and you'll need to learn
it's limitations. Not trying to be snarky here, just frank. There are times
that perhaps you may want to consider just parking until the winds die
down, after all, you have all the comforts of home with you and can just
kick back and make a nice cuppa choice beverage. Here in Nevada I am always
amazed when so many of the Class A motorhome crowd continues to drive until
they suffer damage, either by being overturned, or more frequently after a
big blow, lose one of those expensive roll-out awnings. Always one or two
of those along the highway the day after! Free canvas!
