Legal or not, sketchy as well, the newest f350 junk from ford lists 37,000 pounds combined max, with the "right options and tow package". It should be rephrased as " with the right wannabe options "
I would never do that behind a glorified kids toy with a little plastic connector keeping my electric brakes plugged in. I see plenty of disco lights at night going down the road, I'm sure the electric brakes are doing the same.
I'm sorry, that's air brake territory in my opinion, and not light duty truck chassis work, I don't care what's under the hood and cab for engine and gearbox. The farmer that does it with the 4ways flashing driving 20mph holding up a half mile of traffic needs to be respected. Not the sh1tbags taking Tiktoks while ripping down the expressway with his 4 SEMA-weiner trucks on his flatbed towing 34k# , rolling coal with rubber bands on wheel spacers.
You know it.
Maybe you should start to spec out medium duty trucks. 37k is still hydraulic brake as standard territory, air optional. Most tag trailers even up to 50k lbs have alxes with electric brake options, popular with the dump truck crowd. 2 less gladhands to have to worry about melting/ breaking off. When your backing into the paver or conveyer to dump.
I've seen no real reason to like or dislike the 7 way flat or 7 way round plug, one over the other. Fact is they both have issues with breaking, corrosion, wires getting pinched etc. Just kinda something that needs delt with either way. Engines and Trans are mostly the same options as in pickups, some you can option a 9L engine and an Allison transmission, or a whatever flavor of the day stick you want.
Then start specing out whatver flavor of f350-550, 3500-5500 whatver flavor of brand you like, and you'll start seeing all sorts of things changing, brakes, axles, axles ratios, wheel/tires, frames (yes frames change too, even on a 1 ton truck depending on gvwr.) Add nosium. They arnt your grand pappys 1970 gmc anymore.
