Hey Jeff! Welcome back and thanks for the information! The DeeMaxx Disc Brake Kit w/ Actuator item # DE84NR is exactly what you'll need to upgrade to electric over hydraulic brakes. This kit includes everything you need for your tandem axle trailer including the actuator, brake lines, and rotors.
The DeeMaxx item # DE84NR fits your 1-3/8" x 1-1/16" spindle with included inner bearing item # L68149 and outer bearing item # L44649. The brake caliper brackets mount to a four bolt brake flange as well.
What year is your Shoreland'r trailer and does it have a 5 on 4-1/2" lug nut pattern? The item # DE84NR brake rotors have a 5 on 4-1/2" lug nut pattern so you will definitely want to verify that's what you currently have so you don't have to replace your wheels.

My wheels are 5x4.5 lug however, my trailer is single axle, not tandem.
