I beg to point out another fact on this "one way rental" stuff. We left CA last fall. Couldn't get a one-way RV out of the state. Know why? SMOG II regulations. SMOG II regulations ensure that every single truck, rv, u-haul, etc., NATIONWIDE can pass "SMOG II" regulations. Too darned expensive and problematic for most businesses.
my post was about Trailers, not trucks. but that is another point.
