I'm about to step in to the world of RV's/camper's Australia..
I have previously spent 3month's running around America in an Escape Campervan.. clocked just under 18,000mile and spent about $4000us on fuel.. Most of my time on the road.. even on the Major highway's I spent my time well under the speed limit.. got passed by a tone of Vehicles including other Large RV's doing Max speed.. Average millage was in the 17-20miles per Gallon and for a Large V8 which would normally get a 10-13miles/gallon I thought I did a good job..
Basically I was not in a rush to get where I was going.. Slow and easy at my pace..
I currently Tow a 750kg Camper behind a BA Falcon[on gas] and Depending on what speed and head wind I need to top up the gas[43lt's] every 200-250km's..@ 100-110k/hr Mileage is not good..
With 3 passenger's and camping gear fully loaded, no trailer I managed to get 350-400k per tank.. Just cruising.. Keeping the RPM's down and on cruise control..[100-110k/hr]
I'm Getting a Coaster[1993>+] so I want to try to establish a frame of reference for what I can expect..
I'm want to hear from other people, especially others that have coaster no matter what configuration..
- fuel tank size/type of Fuel.
- K's covered.
- Average Speed traveled at.
- Range of a tank if you have it..
- Yeoeleven where are you..?
- Other coaster owners would be good..

I'm with Keith I find I get best results at around 2250/2300 RPM on my 4.2ltr 4cyl normally aspirated 7mtr Hino Ranger bus/motorhome the average over 1000k is 6.7kl per ltr but if I push it up to 2500/2600rpm that gives me 100kph it drops back to 5.8 kl per ltr.
The figures are a little different on our bigger 9mtr 6 cyl 6ltr FD Hino bus/motorhome we only get 5.3kls pre ltr at 2250rpm and even less if I put my foot down on the freeways..lol..

According to Collyn RIVERS, the most economical running 'speed' for a diesel is approx. 2250 r.p.m. On my 4.6 4 cylinder normally aspirated MH this equates to about 85 k.p.h. on the flat in direct drive. Motor homes, high caravan/trailers/boats will develop 'drag' as your speed increases. Even a 4WD type vehicle will develop a lot of drag due to the flatter windscreen, larger mirrors etc. An example is my twin cab ute. At 80 to 90 k.p.h, I will return approx. 450 kms on a 57 litre fuel tank unladen. As soon as I hit higher speeds, my mileage increases proportionately to less than 300 kms. Yet around the suburbs towing a 3 tonne capacity trailer or a 2 tonne boat, I'll get 300 kms (pretty consistently). Same with the MH, when I go over 90 k.ph. the mileage drops through the floor. Yet SWMBO's car has a very low drag co efficient and is incredibly economical over 100 k.p.h. (go figure). Also, higher speeds with towed or high vehicles increases the likelihood of a bingle. When I was a 'Plod', one of the biggest causes of crashes were speeds disproportionate to the conditions which includes vehicle type or towing.
Our rig, Isuzu D-Max twin cab ute & 5th Wheeler. Normal travel with the ute only on the road about 13.5 Km/litre, towing the van at 90/95 km/h about 7.0 km/l
So the Bus will get about what I get with the car at the moment.. and I'll just have to cruse at the same US speeds I was doing.. 85-95km/h[50-60mil/h]
Slow and Easy and Pull over when safe to do so for the Fast manic's..
