My bud will buy an older trailer usually a specialty unit like a sliding axle tilt bed or a RGN either mechanical or hydraulic then haul them out to me for evaluation. They almost always require brake replacements so He considers that he is going to have to spend 3 to 6K or more before buying one. At an auction several years ago now he and I spotted a Traileze hydraulic flip tail with a badly compromised frame right behind the neck I convinced him to bid on it. Anyway he made a bid so low that we could have tripled our money just by cutting it up and hauling it to the scrap and no one bid against him. I bought about 25,000 lbs of stuff with the intention of much of it being turned into scale bait. but there were a pair of long heavy H beams in what I bought. We used those to stiffen the neck on the trailer by chaining them down and had everything else loaded on it. On the way home with our bounty I said you know I bet for less than 10 grand I can turn this trailer into something worth selling. Anyway a thousand dollars worth of T1 steel new brakes including shoes kits drums slack adjusters S cams chambers the antilock valves and sensors air lines hydraulic hoses and repacking the cylinders plus 8 new tires and a little paint and lights the trailer was roadable enough that he pulled it for nearly 2 years. He kept track of the added revenue it brought in over just a step deck or a flat bed and figured it paid for itself in the first 9 months. One day someone offered him too much money for it so he sold it and bought an aluminum step deck and a tandem sliding axle landol with the money from the Trail eze plus another aluminum flat bed the step deck cost him 10,000 and the landol cost 12,000 the flat bed could eventually wind up as scale bait. but I put about 5K in parts and labor in the landol and he has 2 trailers that he can pull Right now I have a 3 axle Kaylin Siebert sliding axle of his to rebuild for him.
