Trailer related... sounds good to me.
I think it is so dependent on the tow vehicle. Bronco we used to tow 2-2,500# but I've towed other EB's on trailers with my Bronco over mtn passes on the freeway... wouldn't do it again but this was 40 yrs ago. 1/2 the traffic & didn't know better.
New 1/2 ton compared to a '70's half ton there is no comparison for braking ability either.
I used to haul boats with F250's from the manufacturer to our marina with '70's F250's & there is no comparison btw the handling & general towing ability btw older & newer trucks.
New trucks are SOOO much better tow vehicles than older ones.
Tongue length, tongue weight, haul vehicle bed length all factor in also.
I don't have any issues hauling the same weight as what the truck weighs w/o brakes on the trailer. City traffic might & speed factor in...
Wa has regulations for axle weight & when brakes are required.
