Not new to RVing, but getting ready for retirement. Currently have a 2019 Puma unleashed 381 5th wheel toy hauler and a 2014 F350 dually. We plan on doing some extended trips once we retire. I have been looking at HDTs. But not knowing what to look for. I have been looking at sites like Ryder and Penske. Found some units at what look like a reasonable price, but not sure if that is the place to look for a unit to have converted or not.
