What is the best travel trailer for two people and two dogs for a three month USA trip?

There are so many different types. We have an F-150 which can tow 7700 lbs. What should we look for in a travel trailer? I want to be comfortable but not over do it! Thank you in advance!!!

Pop up trailers are great, they're not the flimsy screen enclosed types from many years ago. They're low profile when travelling so you get less air resistance, which equals better gas mileage and more safety because there's less cross drafting.
