certainly - remember, it's not always just 'hp', but 660ftlb of torque that get you 'up' the mountains - in 80,000+ miles all over this country, Alaska, and most of Canada - including the Rockies and all other 'mountains'... we've never had an issue. You will pass full semi trucks going up, you'll be passed by empty trucks going up, and you'll let the Exhaust Brake bring you down the other side.... we LIVE in the mountains, we know!
Some folks balk when they see '300hp', but remember also that our 33.3 weighs slightly less than 26,000lbs full loaded - and tows our Focus effortlessly. Some longer coaches weight TWICE as much, and therefore need more hp, of course. Believe me, if you have any concern over hp, I'll race you're new 'Ace' up the mountain, and be down the other side before you reach the top!
Once you've gone to a diesel pusher, you'll understand.
