I will give you my two cents because I own and use an AF, so Im speaking from some experience. This is my 4th RV that Ive owned. As far as quality of construction, you will be very happy with AF. It is by far the best built RV that Ive owned, and Ive had fewer problems and issues with this AF than any of the others. As you already know, they are heavy but you do have a good truck to haul either one. I wont speak for Adventurer because I never owned one. Im sure there Adventurer owners out there that can speak for their brand.
