I said it several pages back. Current trailer weighs less but the one I want will exceed 22K.
As you did for your choice of truck.
Having pulled heavy GN trailers with all type of loads like permitted box containers/wheeled construction equipment/etc your choice of gears will work fine with todays high HP/Torque diesel engines and new gen 6 speed transmissions.
Trailer tow ratings cover all trailer types including RV trailers.
You made your decision so ask a mod or the adm to close your thread ...or your thread will go on and on and on and.......then get locked.
