If your looking at fifthwheels and you have a 3/4 truck. There are a few Fifthwheels out there you can tow without any modifications. I had to look and look but found one that I really like and I have a 2012 f250 diesel and it tows great. I would keep it around 12,000lbs total weight. I located one its 9700 lbs dry and just over 12,000 ;bs total. This is a 2014 Montana High Country and its 37 feet long with good build Quality. Its worth putting in the extra time to make sure your happy with your purchase.
