Hey Chuck,

Converting to electric over hydraulic disc brakes is a very smart idea as it gives you the best possible braking. We do have a kit that includes everything you need for your 2021 Grand Design Solitude 380FL, which is the following:

- Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers # HSE7K-T1

The # HSE7K-T1 comes with all the necessary parts - the hub and rotor brake kit, electric-over-hydraulic actuator, brake lines, and fittings - to install on your trailer.

We do perform installations, but if you don't happen to be in the area, we do have an installer locator which I've linked below for you.
