I'm going to be using my '95 Dodge Cummins 3500 dually to haul a 1967 ford f100 on a Uhaul car transport trailer. I've reserved the trailer and also found out that the trailers Uhaul rent don't have electric brakes. Is that safe? The Ford being towed weighs about 3500 pounds. It'll be a cinch for my truck to haul, but I'm concerned about downhills and stopping power on the trailer. Has anyone towed a load like this on a Uhaul trailer with any problems?
