Hi everyone, I am new to RVing and to forums. I would like your suggestions for a reliable travel trailer (not fifth wheel trailers) under 20 feet long that will accomodate my fiance and our dog for road trips up to three months long (I am an artist). I will be towing with a Chevy Express 2500 extended length van with a V8 and tow package. What are the features in a travel trailer we can't live without, what sort of construction should we look for in both the trailer and its amenities, what add-ons or manufacturers should we stay away from, what sort of maintenance do we need to be aware of on these trailers? What can we expect for fuel efficiency and how can we increase it? We have done a little RVing with a three horse trailer and living quarters in front, but that's it, and never more than a few days at a time. Thanks in advance for your help.
