i tend to give folks wide berth as well,
you just never know when things decide to leap for freedom from a truck
were we stayed for a while in a state to remain nameless we used to joke about the 30th of the month as everyone was playing musical trailer parks and would stack their belongings sky high with no ropes and drive around town to the new abode
otr truckers I find are about 70/30 for being cordial/rude
most wave at us when they pass, but some scowl...usually at truck stops, once they see how crippled and young i am , seem to be friendlier than when they first eyeball me as i drive up.
either way i drive defensively but courteous
always looking ahead as far as i can see.
i have had to pass a car with the motorhome on a two lane though
