Traveled across the country with my teardrop this year. Oklahoma to New York down Route 66 all the way out to Santa Monica.
Joy(our trailer) weighs about 750lbs empty about 850lbs fully loaded. It is so light that I was getting 16-18mpg while towing. It has been a great little camper.
Towed this to glamis over Halloween weekend. I would say about 2000 lbs including all the gear. 2500 lbs max. Give or take 400 miles round trip. Got there on half a tank doing 60-70 mph
