I'm going to go the opposite as everyone here. The issue with not having trailer brakes is in emergency situations and that no brakes can be hard on your truck brakes. You would still have the emergency e brake, so if the hitch came undone or something, the chains and brake pin would pull and trailer would stop - hopefully. But going 35 miles isn't a big deal if you are careful. Don't follow close, start stopping way in advance of a red light, etc. If anyone here has a newer chev - not sure about other trucks - if you get the dreaded "check trailer warning" you no longer have trailer brakes. This happened to me a handful of times just a couple weeks ago coming home, a couple hundred miles. I pulled over more than once to check my connection, check my brakes with my controller, etc. More than once, I didn't have trailer brakes. More than anything it is just hard on the truck. My last stretch leaves the freeway then goes 10 miles of stop lights with a large hill. Near home I realized my trailer brakes were again not working. I think it happens when I hit a bump. Anyway, no issues stopping - my trailer is 11K lbs. Not ideal, but in no way was anyone near me in danger. I often don't even use my brakes as I start slowing down way in advance. It doesn't take much to take your foot of the gas and let the drag slow you down.
