I need to buy a trailer brake controller for my 3500. What is a good one? I was looking at this one and need to know if it is any good. P3 - Brake Controller w/OEM Harness - Tekonsha Control : eBay Motors (item 300402790373 end time Mar-07-10 23:30:00 PST) The truck is setup with a gooseneck and will be headed to Houston TX next weekend for TX2k10 and will be towing a dual axle 28 foot enclosed. At most I will be pulling a 3 axle trailer.
