I bought this as a gift for my son. It's a great little trailer.
The trailer shipped quick, and UPS rolled it down the driveway on a pallet jack for me. I assembled it the same day it arrived. It took me a little longer due to a couple of issues:
The design has changed and there is nothing about it in the instructions - I looked online and watched videos - still nothing. There is now a new hole in front of the spring mounting hole in the frame - about 2" from it. That hole is now used for a bracket to mount the fender - the other bracket mounts to the rear spring bolt. This mounting method for the fenders is way better, but there is no info available about it at all, and the brackets are not on the parts list. The other issue is the grease zerk on the hubs. I don't know what planet it's made on but I've never seen it before. It's smooth so no shoulder for the gun to clip onto, and smaller diameter. I have a lot of grease tools and nothing fit. I finally pulled the zerk and stuck one of the tools into the hole - it fit tight enough I could pump grease in, but when I pulled it out an inch or two stream of grease came out too.
Other than that assembly was good - all of the parts were there once I figured out where they went. The trailer is great - the instructions are not.
