I was towing a 33' Coleman 2855BH with my 2016 Ram 1500 with hemi and 3.21 gears. It did good on shorter, slower trips like back roads, but on the highway it was just too much. I had a BlueOx Swaypro, airbags, and e-rated tires on the truck.
This year I upgraded to a 2019 Ram 2500 with 6.4 and 3.73 gears. I towed that same camper on a 4,000 mile trip from New Hampshire to Badlands, SD and back. The truck can handle the weight without issue and there was plenty of power. While staying at the Badlands KOA I talked with a couple that run a Duramax with a 38' 5th wheel so we started talking about our trips (he is from CA). I explained that even with the sway control, it's still tough driving a bumper pull near the great lakes, through the White and Green Mountains in NH and VT. I asked if the 5W is really a difference and he said that is his first fifth wheel after coming from a travel trailer and the difference was night and day easier to tow a 5W.
Overall, I felt that the towing experience of trailers left quite a bit to be desired and my wife saw how much work it was to tow the travel trailer in the windy conditions. I didn't have issues with trucks passing, just the wind made the camper dance.
My wife was opposed to upgrading both the truck and then the camper at first but when I said I'm not doing anymore long trips, that sealed the deal because we like doing a destination trip every other year. We searched for months and chose our Cougar 30RLS. Like your trailer, it's "half-ton towable" and even says so on the front cap. Would I tow your trailer or my 5W with a half ton...NO. At a rest stop while fueling up a guy commented and asked if it is really half-ton towable and I told him honestly, no, it shouldn't be. Too much trailer for the truck and my 5W is only 34' long.
With that said, you have a phenomenal trailer, it's just going to be a bit of work to get everything set up. If I can offer one bit of advice; if you're looking for a used tow rig, and it's going to be a gas truck, the 8 speed is worth it behind the 6.4. If you want to future-proof, find a 3500 Cummins- the 2500 doesn't allow enough payload with a Cummins.
Best of luck, I imagine it'll be tough to watch that 1500 go.
