KZ

KZ brand seems like it has pretty well designed trailers. They don't have anything lighter than 4000 lbs GVWR but they manage to fit a lot into a small space and keep it lighter than many of the competitors. They have a number of options with pop out tent beds which gives you a lot more sleeping capacity with a lighter weight if you are willing to live with the caveat that if you get rained on you have to at some point pop everything back out to dry out. If you have a tow vehicle that can tow 5000 lbs these are worth looking at.
