I got them to install electric brakes on my Hauley, so if you request it, they can get it. The frame mfr actually orders and mounts the axle
, and they are the ones that do the brakes. Snoozy just has to specify what they want delivered, then they mount the body onto it.
With the Hauley, I'm constantly changing the weight
as I make deliveries (unloading as I go about my route). Surge brakes would have been problematic to adjust under those conditions, I think. That is why I required electric brakes.
