If you are anything like me (and I'm guessing you are since you found this article), you bought a trailer to haul around your first-born before she (or he) could hold her head up. Now that you have many adventures with your child(ren) in tow and passed along the cycling bug, it's time to re-purpose that well-worn trailer into something useful again.
Here's how I converted our trailer into a cargo hauler worthy of a long trip.
Step 1: Teardown
Our trailer was used and abused for years. With a weight limit of 100 lbs, it could handle the both of the kids inside - until they just grew too big to fit. By then, they much preferred to ride on their own. So, we must begin by taking the old trailer apart.
Start by removing all of the nylon canvas bits that you can. Everything on our trailer was held on with nylon webbing, plastic cinches, and plastic buckles. There are also three metal supports which thread through loops on the canvas sides and back which must be removed.
Ours was designed to fold down so it would fit in the trunk of the car. I think we did this once. Anyway, after removing the roof, there are two large knobs which hold the side supports to the rear support (second photo). Once these are removed, the bolts at the front (photo three) and the back (photo four) should be removed. Once the supports are disconnected from the main frame, the remaining canvas should fall off. If it doesn't, go back and look for velcro loops or straps which you missed.
