Now that I'm towing with an Escalade 6.0 ESV I am considering the advantages of a weight distributing hitch. I know that this set up will not work with hydraulic brakes but why would it not work with electric over hydraulic?

Anyone seen this done?

i use them, it works great

they will work for either or,,i use to use the spring bars on my old snoemobile trailer when i had my 1/2 ton suburban with surg brakes,,stoped fine with no issues..

EoH no problem at all

Surge, if not set up properly, the tension applied to lifting the tongue will restrict the actuator movement diminishing braking. Not good.

With your setup, I would certainly switch to EoH. You will be pissed you didn't do it years ago.
