As far as Kaufman trailers, yes I pull a 55T Kaufman lowboy. They are a cheaply built trailer. IMO they are for guys just starting out who need a trailer but can’t afford any of the big name tried and true trailers. I would buy one only under that circumstance, until I could do better. I have many nits to pick with the Kaufman I pull BUT it hasn’t had a mechanical failure yet even considering I have had it slightly overloaded a few times. If I used it everyday I don’t think that’d be the case though.
