Our last RV was a 2007 Rockwood Ultralite 2502 travel trailer. Ordered it new online.
It's right at 4000 lbs empty, but with all the options. No slides. Very little storage. 25' long. The next model, with a slide, added over 1000 lbs at the time. Even hybrid TTs weighed more than this one.
The get the weight this low, the trailer is 6" narrower than their other models, the wall frame, bed frame, and dinette frame, are all welded aluminum. The trailer frame is steel.
The upside to this TT is even a mid sized SUV (not a crossover!) can tow this easily. The downside is the limited space. Fine for the two of us, and a small dog.
But we are now close to retirement, and recently bought a Class A. The TT will be sold to our niece by the end of the month.
