Hi, newbie here. We've searched online and in person and are having a hard time determining which TT is built well and which are cheaper. I've read responses that say there are higher end in each manufacturer. How do I find which models those are? We are looking at 28-30' real living TT's since we can't afford an Airstream. TV is 2015 F-250 club cab with trailer tow pkg. Just the three of us, retired couple and 70# dog. We plan to travel and live in it for 2 Summer months to get relief from AZ heat. Would love to hear which TT's have well-built frames, cabinets, drawers, etc. Thanks in advance!
