Question for current or retired truckers

RV drivers in general aren't bad. However, there are some who just don't extend the common courtesies of driving a large vehicle, such as keeping right unless passing, not attempting a pass on a grade when they don't enough power, not creating a gap for merging traffic etc. However, this same issue applies to many of the low-paid, barely experienced drivers working for some of the low-bid long-haul outfits.
