First of all, I'm no weight police, whatever people choose to tow is their business and if it works for them that's good enough for me. Looking at the
Open Range website under their light fifth wheel section shows most of units with GVWRs of 10K or so, listed dry pin weights are understated, not even 20% of their listed UVW. You have a very capable TV, but real world loaded for travel pin weights will be much heavier than listed by the manufacturer leaving very little available payload. Does that mean it's a no go, once again it will ultimately be your call. We all know your TV can pull it, hard to say what level of towing comfort to expect since this 5er is significantly heavier than your current TT. Some TVs perform well near or just over towing capacities while other TVs struggle immensely anywhere near stated max capacities. There's no clear cut answer, but if these 5ers are truly half-ton towable as stated by the manufacturer, you certainly have the half-ton that's capable of doing so. Good luck and let us know how it works out.
