Driving Diesel verses gas coach

For those of you having experience driving both types of coaches (gas and diesel): I'm I correct that the heaver diesel coach is more stable in the wind and with truck traffic, quieter, pulls stronger up hills and bounces and weaves less on ruff roads.

I would say yes to all of those.
Only thing I would add is the gas class A's seem to me to be better light to light.
Maybe thats just me but I work on a lot of f53's and they all seem faster from a stop to 30 mph than my Dutch Star.

Nope: Not necessarily. I have spent thousands taming my 40 ft Monaco product. My last A was a dream to drive and would out-run the 400ISL. The 40 footer is much heavier and gets much better mileage than any of my previous gas rv's.

You need to test drive any rv on the highway and hopefully with some wind. You should not have to saw the steering wheel back and fort to keep it down the middle.

That said, a proper chassis setup well will indeed be quieter and be a pleasant drive.

I would agree with commented diesel goodness as well. Additionally braking is enhanced by the use of engine braking mechanisms. Hill climbing can be offset by the diesel being a larger and heavier coach. As for the acceleration, a diesel gains momentum rather than quick acceleration.

Generally yes, but maybe not 100%, as YC1 noted. A typical diesel pusher has a longer wheel base, is heavier, has a more rigid chassis, and often a superior suspension. That doesn't guarantee anything, but they are all plus factors. However, an overloaded, poorly configured DP may still wallow and wander, while a well-set up gas chassis may be quite docile.

Having owned both gas and diesel MH's, I would definity say yes to your question.

My Excursion was a 35' diesel and it was a handful to drive. All over the road, got pushed by anything passing it, cars or trucks. Some people tamed them with new shocks and tires. We ended up buying a bigger coach and the difference is dramatic.

I'm sure there are lots of gas coaches out there that drive better than my excursion did. Your gas vs diesel decision should be based on other factors. Mainly 40' and larger coaches are almost all diesel. If you're going to tow heavier cars and trucks, diesels would be more appropriate.

Or if you just have to have a diesel. Not logical or defendable, but it's your money.

We can consider all variables here (properly/or not set up etc.), the fact IS,......two coaches (gas and diesel) set up as good as they can be, put side by side,.....diesel WILL outperform the gas one every time (I had both). There is no comparison. My DP doesn't care if it's on the flat, or climbing hills. It doesn't care if it's passing eighteen wheelers (it doesn't get passed by them.....EVER!), or if it's windy. No struggling, no overheating, no noise, and torque galore. Not to mention airbags (comfortable!). Happy DP owner here obviously.
