I've got a 2020 Bigfoot 25C10.4 that I'm selling, only used it for a couple of weeks, that would be perfect for your dually. It's currently in Calgary, Alberta but it shouldn't be impossible to get it transported to the US (since truck campers don't have to be registered, it's essentially just cargo) and with the currency exchange it definitely works in your favor.
