Hey Dusty, we have the perfect kit for converting your 2023 Grand Design Solitude 380FL to electric over hydraulic disc with the Hydrastar kit part # HSE7K-T1. We know your travel trailer has a tandem set of 7k axles with an 8 lug bolt pattern which is what this kit was designed for exactly. It comes with everything you'll need too so that makes it easier plus the actuator that comes with it is our favorite here because of how reliable it is and how quick reacting it is as well.

Hey Dusty, how did the Hydrastar disc brake kit work out on your Grand Design Solitude 380FL? That upgrade should make a big difference in braking power. Sharing how it performed could help others thinking about the same conversion.
