I'm not sure how you are but I put a lot of thought and go to great pains to find stuff that I like. I'm rarely successful really because most things now days are built so cheaply it's tough to find those unicorns that are both affordable and reliable. Once I do though I hang on with a death grip and it takes a small miracle to convince me to try something else.

It sounds to me like you're more than happy with your current set up so my question would be why change it? As long as it's doing what you need it to do and you're happy with it I see no reason to stir the pot so to speak.

To answer your question.....it's like asking a group of people which is better....vanilla ice cream or chocolate? The answers are going to come down to personal taste.

In my opinion....

Please do not attempt comparisons like this - they are apples and oranges.

A gasser is a wonderful thing and they do what the do very well.

A DP is a wonderful thing and they do what the do very well.

A more entertaining comparison would be a Ferrari LaFerrari vs a Ford Escort.

Also, as Skip says, when the MH gets larger a diesel becomes more desirable, or necessary. Ever see a gas powered 18 wheeler?

Just my 2c.

Yes, the company I once worked for had one old gas tractor. In a word, it was a dog! Used it mostly as a yard truck, but it would pull a trailer on the road if you just had to. When I became the GM, we scrapped it. Along with a bunch of old diesel tractors with engines that were too small.

Numerous threads on this subject... Search and read through those threads and you should get more info on the subject.

getting 9.5mpg on a gas RV is extremely impressive to say the least... Is that calculated from the RV computer or from a calculator?

I have always had gas, cheaper to maintain and I do not drive 10k plus miles a year. Presently looking for a used DP, for me I wouldn't say it's better... It's easier to drive/live with

On smaller RV's, it's a personal choice on which way to go. Larger motor homes, it's a no brainer (not to mention, there are no gas driven big coaches for a reason )

Diesel is better for big class A's, but whether its worth it depends on how many pounds of gold you have. For a small class B or C, gasoline has advantages beyond just being cheaper.

One issue with diesel pushers is rear overhang necessary to fit the engine, transmission, and driveshaft between the axle. That limits how small they can be, with about 34' being the limit. Shorter examples have been made, and generally not sold well.

You diesel people are so nice. The diesel engine is far superior to the gas engine thats why it costs more. I have the good apple to apple comparison going from a gasser gross weight 22000 to a diesel gross weight 25000. Thats pretty much two apples !

The diesel climbs better pulls better, gets better mpg revs lower and lasts longer. Gas engines are used because they are cheaper.

Our 2002 DSDP had the ISC 350/1050. I put a Banks kit on it so it was 435/1200. The mileage didn't go up nor down from 7.5 or so and we always towed our Odyssey. After 13 years of ownership I can say the DSDP was the best MH we've ever owned and we should have kept it.

That mileage is about the same as we get with the present Magna and towing the Ody. at 7.6 mpg but it's much heavier and far more powerful.

Smile Are Diesels Better

I am a DP owner with a '99 Scenic Cruiser by Gulf Stream and I have had gas also. My reasons for choosing diesel over gas are: engine noise and heat are 36 feet behind me. Flat floor vs. dog house. Heavier duty chassis. A much shorter drive shaft. Air ride vs. no air ride, air brakes vs. no air brakes. 22" tires vs. 19". Longer engine life: I do not know what a Cummins warranty is now; but, it had been 150,000 miles and no RV gas engine is going to see that on an odometer. Higher trade/resale value. As you can see the amenities for me are the swing vote and not the fuel type per se. Frankly, I could care less if it ran on Pepto-Bismal ! But, when push comes to shove it is what you the user will be comfortable with . However you choose to go just have fun.........Ken

Can't beat a pre emission diesel. After 07.5 everything got dpf filters and egr which brought reliability and fuel milage down on Diesel engines.

First of all "better" is a subjective term. From the sound of your post I would say you should stick with what you have now and are happy with.

In general and theoretically the diesel engine is better suited to a large heavy vehicle like a motor home. But of course that is only in theory and it depends on its application. We used to have a gas motorhome that was very fast, got pretty good milage, and was quiet. That was a GMC motorhome. Only 12,000 lbs and a hot rod Olds motor. On the other have we rented a number of 28-32' class A and class C motorhomes with gas motors that were very loud going up any kind of hill. Those motorhomes we rented would have operated much better with a diesel motor that was properly noise insulated. Why, diesel motors have more torque for comparable size motors. Lots of torque means it is much easier to go up hills.

The only problem with this is that makers charge lots more money for diesels and maintenance costs more. So maybe the "better" definition may swing to gas motor because it is cheaper.

In the end the best motor for you is the one you like the best and fits your budget.
