Looked up the brochure for the 2008 Meridian. Didn't see a 39K but there is a 39Z.

From what I've come to understand the 6.7 was recently upgraded to 360HP/800FtLb and it has some mount of get up and go. It is also now generally coupled with an Allison 3000. If you have the older configuration with 340 HP/600FtLbs and a 2500 Trans, you may experience slow go on hills. you should also check the GVWR and the GCWR to make sure you are not over loaded.
On long hills, regardless you want to be in what ever gear you need to be in at what ever speed that give you in order to keep your RPMs at or slightly above 2000. This should provide the airflow you need to keep it cool. It may mean you go up certain hills at 30mph.

I have a 6.7 and 700 ftlb torque and have no issues towing a 4700 lb Traverse, I think you will be fine. Besides even if you had 600 HP and 1800 ft lbs, you probably won't be able to get around the guy in front of you going up the mountain at 45 mph.
Comming down the other side we can all do the same speed. LoL!

While you're somewhat correct, there are differences in the two engines. I was simply inquiring if he DOES IN FACT have a DESIGNATED 3126 in a coach THREE YEARS NEWER than the year it was last reported being installed in.

True. I guess when I read the year and 3126 I knew he was talking about a C7. When we bought our '03 it was one of the last 3126s Newmar installed in a MH so I knew the pipeline was about empty. If I remember correctly some of the '03s had C7s in them. I couldn't imagine there would be any true 3126s around 3 years later.
Then again our '08 has an '06 spec Cummins in in so anything is possible.
There are 24 hours in every day - it all depends on how you choose to use them.

3126 or C7, I have not inspected the engine. I only have read the owners manual which says both on the cover. I do not know how to tell the difference. Let me know how so I will know what I own.
