Since light weight seems to be a priority with your tow vehicle, you may be well advised to take a look at hybrid trailers with tent ends. With them you get more living space and lighter weight than with a completely hard sided trailer. Another possibility for a very well made trailer is the Trail Manor which is a form of pop up but will all hard sides. They have a great reputation and are very light weight and easy to tow. Set up is done in a matter of seconds.
