I have seen their flatbeds bring pulled by condos and midroofs. I don't know if they have a certain criteria for which truck to pull which trailer. I have seen a mix of them. It may be based on truck availability at this point in time.
Tell them you eventually wanna train and they will pull you in condo, otherwise most drivers get lightweights, basically they pull the passenger seat and strip few other things out so you can haul heavier loads
