All time best trailer ever to buy! The only things steel are the axles and the tongue. You can easily pull this with a 1/2 ton truck, or an SUV like a Tahoe. If you put it on a diesel truck you won't even know it's on. I had this trailer for the past 6 years GNCC Champion Chris Borich had it since 1998. It just painted last year oxford white I had all new hubs and brakes installed at that time also and 4 months ago I repacked all the bearings and looked over the brakes. The tires are about 1/2 tread they are about 2 1/2 years old. All the lights on the outside of the trailer work and the 12 volt dome lights inside. The inside shows use I was considering redoing the Aluminum sheeting on the inside but just never got to doing it. I keep this trailer either in my car port or next to my shop it's never stored other than a hard surface. Feel free to call if your interested thanks Wes 570-617-8883
