Sorry, not getting email notifications for some reason. It doesn't have side rails, just big angle that sticks up a few inches from the deck height. Here's a pic when it had some awesome plywood over the trashed deck. The PO was my FIL and they used it to haul roofing supplies. I took 3 or 4 boards out of the middle so it's lighter and I don't get asked to help people move. I think my old Aztec was supposedly like 1500 lbs and this one seems even lighter.
My dad has an angle iron Big Tex tandem trailer that is 35 years old or more. It has pipe side rails and has been overloaded most of it's life. He still uses it all the time to haul his Kubota tractor around (about 7k lbs) and hasn't done squat for maintenance on it... ever. I have no idea what it weighs though. My brother uses it often, and has damaged it several times over the years. I've repaired a few broken crossmembers for him.
Does yours have the side rails, Nate?
Maybe I should just copy my Dad's trailer, but with a single axle and shorter deck.
