no problems going up or down long grades. Just take your time. I don't have an exhaust brake, but lower gears work fine. I keep the engine at 2000- 2500 rpm in a gear that is not lugging going up hill and generally the same gear going down long grades. The engine and tranny run mid range temp wise. Some folks like to race up hill for some strange reason, but I set the cruise in the gear that is appropriate and enjoy the scienery. No reason to punish your TV. I have traveled all the Interstates and highways across the Rockies over the years and have never had a problem---However I would avoid some roads like these pulling my rig.
