Gas vs Diesel (I've read the FAQs!!)
Hello to All, We *still* have the Thor Jazz in my sig, and it's still a going concern, but the wife is up for a change and "we" are wondering if a Class A would fit the bill. Many of our trips are ...

I have a 36' DP Cummins 275 with an Allyson 5 speed tranny.
My experience going over the grapevine is 45-50 mph. The only problem with that is it is too fast for the trucks and too slow for lighter RVs. I do weigh in at 25,600 with my '11 Ford Ranger in tow. I get 11 MPG
I previously had an International 4dr 4700 with the 250 engine and an Allyson 6 speed tranny pulling a 30' 5er. My total CGVWR on that was 21500 lbs. I drove the Grapevine at 40-45 mph and got 9.8 MPG
I also drive the Siskyous (I feel steeper) and do pretty much the same thing, with both rigs.
I am happy when someone passes me 55-60 mph, because I usually pass them stopped for fuel somewhere down the line.
Now, I am not unhappy going up/down both of the grades I mentioned at 40-50 mph. I really wouldn't want to go faster. Don't forget the 25,000 lb. weight and stopping.
