I meant to leave you our worst and best mileage
(ISC 8.3 -350HP)
- me driving very hard 6 to 6.5 (I generally also run the generator-same fuel source)
- me, average, most times we are "towing VUE" - 7.5 (possibly some light generator use)
- wife, at times (most times) 9 or slightly better (no generator) - she has hit 10 mpg (but that trip took forever!) 
That should be close - the generator messes up mileage most times - if we are running the generator while driving, the coach chassis AC unit is on too

In february 07 I went to daytona in my 35 foot winnebago adventurer and spent $222.00 on gas took my new 43 foot tourmaster in july for $133.00 rode better and pulled 4500 pound toad with ease...I dont worry about mileage I worry about cost..you have to take the cost of the two fuels in consideration ..jim k

Hi there! I have a very similar coach to the one you are looking at. There are a few things that you should watch out for. The one you posted only has a 4-speed transmission which is a negative, most have 6 speed transmissions, which helps in hill/mountian climbing and MPG.
That coach will probably get you 8.5-10MPG with that engine driving at 55-65MPH.
My coach has a 330HP CAT engine with a 6-speed transmission and pulling a 24' enclosed trailer that loaded weighs about 7000lbs I get 8-8.5MPG going 63-68MPH.
If I drive a lot faster say 70-75, then the MPG drops down into the mid 7 range.

I know there are significant differences with maintenance and repair costs. I've often read "better MPGs on diesel" but realized I actually have no idea how much better.
I am looking for something like this 2000 Winnebago Journey at PPL:

Any help with diesel MPG info is appreciated...
Thank you!

The propane generator would be a deal breaker for me....that being said, if you're gonna go on a long trip like that, you DEFINATELY need a diesel coach.

I agree with prevous post about the 4 speed transmission. Drove one of those when we were upgrading from gasser, and did not like the 4 speed. Also that coach you're looking at has the old style freightliner dash that is all one integrated piece. If you lose a guage on it, you can't just replace the guage, you have to replace the entire panel (much $$).
On my 2000 HR Endeavor 330 cat 6 speed allison towing 4400 lb toad I've averaged 8.45 mpg over 33,000 miles running about 64 to 65 mph. This also includes fuel used by the diesel genset, and it is running at least 70% of the time.
Good luck with your adventure.

Most of the time, choosing Gas vs. Diesel in a type A motorhome is not about choosing the power plant, it is about choosing the size of the motorhome.
Type A gassers range from under 14,000 pounds and 24-foot to 24,000 pounds about 38-foot. A gassers used to be available under 11,000 pounds, before slideouts made them heavier. Traditional A diesel pushers start at 26,000 pounds and 32-34 foot, go up to 40,000+ pounds, 45-foot.
More recently, front-engine diesel motorhomes have been produced that overlap more of the gasser range, i.e. small diesel motorhomes on the Sprinter chassis at 24-28 foot under 11,000 pounds, and larger front engine diesels 36-40 foot around 22,000-25,000 pounds. You will soon see more front engine diesel motorhomes, using smaller diesel engines not now used in motorhomes as one of the two currently used gas engines disappears from the market.
In the region of size overlap, the diesel can be expected to deliver at least 15-20% more mpg because diesel fuel is more dense by that much, and energy content is by the pound (though we buy by the gallon). You might see 25-30% better with the right driving style, because a right-sized diesel engine will be in a more efficient part of its operating range during cruise, compared to a one-size fits all gas engine that might be too big for a small motorhome and too small for a really big one.
The Journey you are looking at is in the size range where diesels overlap big gassers, and the diesels are much more efficient and pleasant to drive. I would not buy a gasser that big. If that's the size you want, you should be looking at diesels.
What you can't expect, is a 45-foot, 40,000 pound diesel motorhome to get signifcantly better mileage than a 14,000 pound, 26 foot gasser.

MPG for any coach varies depending on miles on engine, condition of coach, weight onboard, terrain you'll be driving in, driver habits, speed, winds, tire pressure and more...Most broken in diesel engines of the age you wrote (a 2000) may average about 8 to 10 mpg if the whole coach is in great shape. But it could be as low as 5 to 6 mpg.
You just won't know until you take the coach out on a very long drive where you can try to get an average over many different conditions, speeds, etc. Until you have it loaded with your belongings, water, fuel, etc. you'll not know what the exact milage will be. Try to find out what mpg the previous owner got. If you are new to this coach or motorhomes it will take a little while to "learn this coach". You will learn how to manage the coach for the best mpg.
I'd budget for the lower mpg then you'll not be underbid and be pleasantly surprised if you do better.
