I remember those days. I was a kid and my family towed trailers in the late '50's and '60's. My dad generally bought new cars every 2 years and we had 5 cars from '58 to '69' They ranged from a '58 Ford wagon (292 V8), '59 Chevy wagon (235 six), '61 Chevy Nomad wagon (283 V8), '64 Impala wagon (283), '66 Caprice 2 dr, HT (283 V8) and a '69 Impala 4 dr. HT (396 V8).
They all seemed to tow well, little sway with the Equalizer hitch, heavy suspension, etc. We drove through the Rockies with the Chevy 235 inline six, no probelms that I recall. Also no air conditioning back then, worked fine.
