Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
We are beginning our search for a used deisel pusher. We've looked at some beautiful rigs with both CAT C-7 and Cummins engines. Does one have a better or worse reputation than another? I keep hearing that Cummins is better, but I have no personal experience. Does one provide more torque than another? Any suggestions would be great. Thank you.
I hold preference on Cummins , Just on serviceability alone........as far as Engine size , that will depend on travel areas...are you towing....overall cargo on board.
I run a 500 when I go up the mountain towing I want it to go when I ask it......I dont want to be in the breakdown or truck lane at twenty trying to top the hill.
alot is going to depend on your budget and preference...........as far as service. an engine is only as good as the service it recieves, so if you are looking used make sure a complete service record is available.........as far as price....NARDA is not accurate...most units sell 20 to 30% lower from the factory.
good luck on your ventures

Welcome to the forum. We have a 400 ISL Cummins in our Monaco and it hs been flawless so far. I would not let engine alone be the deciding factor in a MH decision. The CAT's are just as good an engine as the Cummins. There are a ton of MH's out there that have the CAT's.
You'll also find a lot of engines in the 350 HP range on both. If you visit several MH forums you'll find folks are perfectly happy with their 330's and 350's . Just take the engine as one piece of the puzzle when looking at MH's in your budget range.
Rocky, you might also run into some Detroit Diesel engines, such as the 6V92, 8V92, or S60 (aka Series 60). The 6V and 8V engines are two-stroke engines, while everything you mentioned and the S60 are all four-stroke engines. There are some who have limited their searches to only those coaches with the two-stroke engines, but they are few. Most of us have learned enough that, as Ken says above, the engine is only one part of the puzzle.
Do your research thoroughly. Decide what you will do with your coach, what you needs and wants are, and what your budget is. Many people recommend keeping back $10,000 or so to spend on repairs and upgrades that you feel are necessary to make the coach meet your needs and wants.
PM me if you'd like a summary of our researches and what we've decided would be best for us. Please remember that your needs and wants aren't the same as ours' or anyone else's, but you can and should use their questions to find your own answers.
Don't be in a hurry to buy something. Look for quality first, maintenance second, and floorplan third. Enjoy the hunt.
The mid-range diesels that are in most DP motor homes are rated for a 500K-600K miles if properly maintained. Most motorhomes hardly go that far in their life. One make is as good as any. Most people have their preference for one reason or another. I'm partial to cummins because that's what I have but nothing sounds like a cat c-15. The most important rating on one of these engines is the torque. Mid-range motors run between 600 and 850 ft lbs. These are smaller motors than the motors in the big trucks but handle a motor home well. The 350 horse units might be around 1100 ft lbs depending on the motor size.

Thank you all for your great advice. We found a '04 Beaver, 38 ft. with Cummins 330 HP and 950 torque pounds. We are waiting for paperwork to be finished and might be camping over Christmas with any luck. Thanks again for all the advice.
Thanks! I checked your website.....Nice! My brother is a full timer www.happy-wanderers.com and they love it! I'm looking forward to doing some traveling myself.
Another thing you can do if desired is to have the chip flashed in your 330. By flashing the chip you will increase the 330 to a 350. I have a friend that just did this very thing to his 330.
Although I would wait and drive it just the way it is. I only mention it as an option.
One thing about these beasts you don't want to get in a hurry when driving them.
Thanks again, I am not in any hurry since this is my first deisel and I have a lot to learn. I have been driving a Winnebago gas and now moving up. I'll let you know how it goes when we get going. Thanks again.
It is a small world! I'm sure a lot of people know Larry and Connie since they are big into websites, blogging, camping, RV'ing, etc. I use his website all the time for looking up things. Maybe we'll run into you someday. Happy travels.
