Back in the "day", we backed a Bronco up to a trailer and TOWED it!! lol
My Dad's '69 ended up towing a 16' Kit Companion trailer for 5-7 months a year all over Canada, Alaska, SW, Mexico, CO, etc, etc. He had a equalizer hitch, electric brakes and drove careful. Probably towed that trailer 20,000 miles... at least. Sold his with 186K miles . I learned to drive in it.
My '68 Bronco towed a light camp trailer for 6 weeks at a time and then a 13' trailer. No PB or PS for years. No equalizer, no swaying. We would tow up to the Yukon, BC, Montana, CO, 6 weeks at a time... NO issues. Can't remember the weight, we didn't care back then- we did what everybody else did. Bought a trailer that didn't look to big and towed it. No accidents, no "I met God" moments. Just drove with some sanity. My trailers never had electric brakes.
My Dad's 16' Kit did. Only once in 186K of driving did he have an "Oh sh#t" moment and when I upgraded his 302 to a 4bbl, headers, dual exhaust he could downshift at 50mph and pull out of trailer sway situations (readjusted tongue, equalizer hitch etc after that) but he ran all over BC, Yukon, NW Territories with 8-9% grades for MILES... no issues.
Just saying some common sense is needed when towing. Yeah, we were probably overweight back then... most everybody with wood paneled station wagons towing Airstreams were too... lol
