Horizon sucks.
I used to work for Quality Drive Away, Goshen, In. They have backhaul terminals in Perris, Ca. and Harrisburg, PA. I used to 'cheat' and work for Southeastern Trailer Transport at the same time. Quality out, Southeastern back to Elkhart, take Friday, Saturday and Sunday off, and do it again.
Quality and Southeastern didn't know about each other. He He. Was making about 3000. 00 a week until 2 things happened. Southeastern stopped paying for BOTH trailers being towed and went to a flat rate of . 95/ mile. And then Quality put a flat rate on all freight to CA.

I was like ,Huh? See, Southeastern pulls 2 trailers at a time, but they want to pay the same for a single unit! But I digress, I apologize, I was only trying to give you an overview of the industry.
As far as your fuel surcharge question goes, the shipper sets the surcharge rate. Translation, they will screw you if you let them. That $1. 00 a mile to the truck is FOR YOU. For YOUR business. If the price of fuel goes up, THEN THE FUEL SURCHARGE GOES UP! Or else they will make you swallow it.
The CONSUMER is supposed to pay for the increase in the cost of fuel. NOT THE TRUCKING COMPANY (you)
See, Horizon IS NOT a trucking company. They ain't got no trucks. They're basically a broker. DHayden Trucking LLC is the trucking company. DHayden OWNS the power unit. Without the power unit, them trailers just sit there. Will the broker find another power unit? Sure. But will HE run into the same high cost of diesel fuel? Yup. Will he need a higher fuel surcharge?
Yup.
I wouldn't hook my Dodge to Horizon's trailers for . 90/ mile let alone . 75
Classis Transport is paying . 99 cents a mile...
