Sir, I have a 2020 Precept 31UL and 2021 GMC Colorado (about 4800#). I went with the Roadmaster Nighthawk tow bar, Roadmaster baseplate, Stay-in-PlayDuo by Demco, battery disconnect, and battery charging lead from RV to Toad. Not the cheap route but I have been very happy with the result. I'd be happy to answer any questions you have.
