Dual axle. Lightweight. This is a fiberglass fifth wheel not an Airstream. We tow it with our 6 cylinder Toyota Tundra. I believe it is 3500 lbs. My husband is 6 foot tall and he can walk inside without smacking his head. Good size shower. We bought this to fix up and get out on the road. 2 years later here she sits. We are not handy and are buying one that is already complete. We have made new foam cushions for the sleep area and seats. The refrigerator gets cold, the AC blows but not cold. AC unit also has a heater we did not check. Plumbing seems to work but there is a small leak under the sink in the shower. Needs electric checked. We popped something and the lights turned off. This rig would make a good project for someone. It is like a Scamp or Casita.
