This thread will be fun to watch.
Both Cat and Cummins are good engines, if you need to purchase Cat parts they will
cost you more.
With either diesel engine do not cut corners on maintenance as they both fall under
the pay me now or pay me a lot later.

I responded on the difference between CAT and Cummins on the CC Forum, on that thread you mentioned the Inspire. On this thread, you mentioned both engines and opinions on CC and Monaco.

That is tough as it is too open of a question. Both CC and Monaco have from top to bottom coaches. IMO, you need to determine where in the food chain you would be shopping?

For example, Monaco has different chassis levels as you climb the food chain. CC does too, but to a lesser extent, as from the Inspire on up the Dynomax chassis are pretty dang good.

Suggest you sit back and come up with a list of Must Have's and Nice to Have's, both chassis/mechanical and interior. Then come up with a more refined list of specific manufacturers and models that fit your lists and your budget.

In general, I always recommend buying the best quality coach you can, dropping years as needed to remain within budget. Quality lasts.

So for CC this would put you in the Allure model and up. And in the Monaco this would put you in the Dynasty level and up. (And the equivalent Beaver, Holiday Rambler versions of the Monaco models.) The Monaco chassis '8 bagger' on up for chassis.

The CC and upper end Monaco's have different handling/ride characteristics. The top of the line Monaco's are more of a BMW type ride, while the full CC line is more of a Cadillac ride, that can be upgraded to closer to BMW type with added components. (Not to go race, but I like better handling for just in case emergency situations.)

Side vs Rear radiator
Tag
Aqua/Hydro Hot
CCC
Towing capacity
Etc.

These all need to be factored for what you want the rig to do for you.

On CAT vs Cummins, I'll repeat what I said on the CC forum. Shop condition of documented maintenance and care first, as long as the interior meets your needs. Both engines are good. I also suggested avoiding ISL era with wrist pin problems, and CAT transmissions.

Good luck on your hunt. If you do drill down to more finite lists of models and specific engines, jump back in as this group is great.

Welcome to the forum. Great screen name too!

You will not get a definitive answer to your Cat vs Cummins question... because there isn't one. They're both great engines and I sure wouldn't make a purchasing decision based on a decision between those two.

Comparing Country Coach and Monaco is a tough one because I believe the two coaches have very different price points so it's like asking if a Lexus is better than a Ford.

Best of luck.

We own an old CC that we have had since 2002.

A few weeks ago we toured 8 Monaco Dynasty and Camelot rigs on one dealer's lot. Vintages were 2004 -2005.

Aside from achieving the benefit of slide-outs, bigger engines, and dis-regarding condition, we did not feel the quality was equal to our vintage rig.

Are we biased? Yes.

Have fun in the searching.

We own both engines Cat in the MH, Cummins in the truck. Both very good engines. Only problem we had with the Cat is the Fuel Rail Sensor went out on us last year and we had to be towed to a Freightliner repair center. Cummins engines don't have a Fuel Rail Sensor. My experience the last 14 years is that usually the components that surround the engines will die several times before the engines ever will.

Cat no longer makes engines for new MHs, so most will be Cummins. However, parts are available for both.

Installed fleet of Cummins engines in motorhomes & trucks is around 70% market share. Way more standard than Cat, Detroit, IH (Navistar), etc.
Cat is a good engine, & replacement parts are available, tho more expensive as noted. However, I believe you'll find Cummins has more available service outlets due to the larger installed fleet.

Excellent advise Smitty.

Here is the info on the Cummins ISL wrist pin issue:

wrist pin problem on the 400 was production date Oct 17,2005 - Oct 18, 2006 (Eng #'s 46463798 - 46603939)

Sorry but I do not agree with this assessment. Before I bought the CC, I drove the Monaco and it was like driving a rocking chair, I could probably get sea sick driving one. I bought the CC because of the tight suspension just like the BMWs that we own. No extra components needed to make the CC an excellent driving machine.

No problem Don, different year/era CC's are different. I know the older Gillag(sp?) chassis handled different. And I was test driving 04/05 Allure, Intrigues with a Magna from I think 2006. You also may recall, that National insisted on the soft floating ride luxury ride for CC. So much so that many of my era coaches with IFS had front end control, bottoming and proposed. I added Road Kings and Super Steer Motion Control Units to improve our handling. I think you have a sold axle in your year?

Suppose the year and model differences exist with Monaco too. But the 2002 and newer higher end Monaco's Roadmaster chassis, are known for good handling. (As much as the four bagger with trailing arm Monaco's were known for poor handling.)

You got me in being too general in my comment, and I stand corrected - thanks.

Best,
Smitty

Smitty,
My coach is an '02 Intrigue with the independent front suspension. Matter of fact, I think I might have the last 40ft built without a tag. The 278" wheelbase does make a difference and you have to pay attention that the ride height is set correctly. I did change the shocks to Koni FSD and after 25,000 miles they weren't any better than those I took off. I now have the Road King.

I don't think that National had anything to do with the ride quality as I have driven coaches built before National ruined the company. All have handled great handling qualities.

Don,

Memory is not what it used to be... I checked my notes and they reflect 2000 was the cutover to IFS, with a few Affinty and Magna having it in 1999. That is a long wheelbase on your rig. What CCC does the non tag give you? And yeah, the RK's really helped. I did have our ride height set to the top of the range, Mikee on the Yahoo CC user group recommended this.

I had two sources tell me the National forced the wrong sized shocks into specifically the 2004 Allure/Intrigue models, and with the post National purchase, power plays were going on...

OP - Sorry we semi high jacked this thread!
