I was at an RV Park in Tucson a few days ago and a local dealer had some coaches on Display. We always go and look just for fun, but the 2016 Entegra Cornerstone (45B floorplan) completely "Wowed" us. We love our current Coach and will probably keep it for 3-5 more years, but it occurred to me that since I usually buy used a 2016 may be exactly what I am going to be looking for when we do make the move. We would be looking for a 42-45' tag axle coach, but my biggest complaint in my current coach (really my only complaint) is the somewhat anemic power from my CAT 330 compared to these much larger Engine choices. The Entegra Cornerstone will be on my list but are other "High Power" options I should look at too. The Entegra has 600hp and 1950 ft/lbs of torque. I know the Allegro Bus has a similar set up, but not aware of any others. We liked the Entegra floorplan better than the Allegro Bus. I tow a 4500lb modified Jeep Wrangler and carry a fair amount of stuff (My wife is an Artist and supplies are heavy! Our current MH weighs 31,000lbs and we can really struggle going up grades which in the West are not that uncommon!
Thanks

Several owners of the '07 ISX engine have reported problems here in the Cummins section and also at the Foretravel site.
However the newer ones with DEF seem to be OK.
Newmar also uses the ISX in most of their "Luxury" line.

Everyone does, pretty much. Cat got out of the OTR business totally. DD and Volvo are the only other ones out there, and I don't think either sells in the RV market. Except maybe Prevosts.

I have an '08 KGDB with probably an '07 ISX. The only non-maintenance work it's ever needed is an EGR valve.

All three of the top Newmar models currently use the ISX 600 - King Aire, Essex, London Aire.

No one really "needs" a 600 hp motor home. The power is always nice at times, but is not needed. Our Bus has the common 450 Cummins with 1250# torque. There are a lot of them on the road. With our loaded trailer, we tip the scales just over 50,000#. We can run any interstate in the country and keep up with most trucks and faster than some on the 6-7% grades. Our son has a Mountain Aire with 1650# of torque and there is very little difference going up to 11,000' west of Denver. There certainly is no disadvantage to having extra power, but I would not limit my search for a newer coach to one with 600 hp. Much larger selection when including the 450 hp group that will do everything needed.

While I agree that a Mh with the 450 hp will get you there, I've owned three, there is no comparison to the 600 hp isx with 1950 ft.lb. torque. It's the difference between a Ford crown Vic. and a mustang.
He's right too that no one needs a 600 hp Mh, but you could also apply that to any Mh. While you may not need the 600 hp it sure is fun to drive with the heavier chassis and Allison 4000 tranny. Jmho
