Mike,
That single slide country coach is AWESOME!
To an extent, this seems to be turning into the typical gas/vs diesel thread....
And to add my 2 cents, diesel is better, always, that's why they cost more.
We've had both. The gasser was loud, always. Horribly loud going uphill. It was bumpy, always. It scared the DW. If I was running alongside (her side) a truck, I was deathgripping the wheel and being blown all over the road, and she was FREEKING OUT!!!
In our DP, I pass or run alongside trucks anytime I want. She isn't a fan, but she doesn't freek out or yell. I steer with one hand while eating, drinking, or petting a dog with the other.
In my limited experience, the difference is startling
