Late addition…. I have a 2022 3791RD, which is basically the same unit. Definitely a yes on the disc brakes. I have the electric over hydraulic disc brakes on mine and love them. I spent too many years with units that had the electric drum brakes and didnt want to go back to that. I have mixed feelings on the 8,000 lb axles. If money were no object, heck yeah. But I can tell you that we are full time traveling east to west across the country. We have over 20,000 miles on the unit. I am carrying everything I want and need. I scale my rig regularly. My 5’er axles have never scaled more than 13,400. Yes, I would love to have the 8,000 lb axles. If / when I need to replace them, definitely. But to pull off the 7k axles at this time? Not for me.
Just my opinion - safe travels
