CarnationSailer, Assuming that the brakes are in good working order, and your brake controller is working properly,you may be experiencing a common trait among many RV’s of today....not enough brake for the trailer. Many manufacturers put the minimum axles on their units...meaning that the brake size is likely minimum. In “yesteryear”, before the hydraulic disc brake systems becoming more popular...some of the higher end rv’s put a larger brake system on the axle: example a 7K axle would have the 8K brake assembly. We had a 2001 Teton set-up that way. Lots of braking power when needed!
