Now ive never run a 9/10 car hauler because i like the space of a bigger sleeper, but if i were to run open, the 8 car from cottrell can really move a lot of weight. Ive seen those haul 5 dually trucks with one car. Enclosed, the biggest issue ive had with kentucky trailers and all of the older ones were the 17.5 tires constantly exploding. With those being 500 bucks each that tears in to your profit. The newer ones run 19.5 tires, so if you an afford 180k+ for a trailer, youll save money on tires.
