Trying to figure out best 5th wheel? Advice appreciated

Research, research. It will take time and a lot of reading. The "best" rV for you might not be what the other person finds important. When I purchased my Carriage Cameo in 2012 I researched 5ers for over 6 months. I love my unit and have had near zero problems. I wanted a 4 season unit, constructed well and had good capacity. It is too bad they are out of business. Be sure you can tow what you get, maintain it well, and don't abuse it. Check ratings.
