How much diesel can you skoolie hold?

I was trying to decide how to make this decision. The question that I think would be useful - what is the longest stretch of road in the US or Canada without services? Another aspect - I know that fuel prices can vary dramatically from one state to another. Any dialog? I am not crazy about the idea of carrying fuel cans to store extra diesel. I want it all to be tucked away safely under the bus between the frame rails.

Another advantage to larger tanks is not just being able to get further on a tank but also to have more flexible as to. Where you stop for fuel.

Gasbuddy.com has a trip planner to help you find the lowest cost fuel on your route. With greater range you can optimize your stops and stick with the lower cost fuel stops.

Try it out. Plug in all of you bus & route info, look at fuel cost then change your tank size and run it again. You will see the advantage of the larger tank even when services are readily available.

one tank or two

I have a 40 gallon tank, I am considering adding another 40 gallon tank. 11,000 pound 23 foot long short bus, expecting more than 11 miles per gallon so effectively 800 mile range with two tanks..... have not decided yet

Mine has a "30 gallon" tank (actually more like 30 usable gallons, tank itself is probably closer to 40, from bone dry to overflowing). Since I plan to rack up some miles on it, I feel a considerably larger tank is in order. I'm debating cannibalizing one from a road tractor in the 100 gallon range.


Since mine's a shorty, I only have ~54" between the steps and wheel arch, so using a longer tank isn't an option. I had considered dual tanks, but the other side has the exhaust routed in front of the tire (I could re-route it, but...) and the air tank (I'm not so into relocating this). So the second tank is out unless I put one behind the drive axle between the rails. It can't go on the right rear because wheelchair lift, and it can't go on the left rear because tool box.


As I recall, a 25" diameter tank, 52" long is close to 100 gallons. (Some quick math shows ~25525 cubic inches = ~110 gallons, but tank makers rate under that for expansion). At ~10 MPG that would give me a mathematical cruising range of 1100 miles, but probably closer to 800-900 comfortably, and realistically probably half that before I'll want to stop and rest, eat, and whatever else.

100 gallons here. The Crown Super IIs that originally had methanol engines have huge tanks, I think about 200 gallons, because methanol has lower energy density than diesel, and they kept them when they were later repowered to diesel. I had thought about putting in an extra tank between the frame rails just ahead of the fuel tank, but I've now used that space for my emergency air compressor instead.

My rig has a 100gallon tank, it's mounted in the very rear of the bus behind the axle. I get about 10 1/2 MPG so I can easily go 1000 miles on a full tank. It's a nice thing to have.

Mine has a 65 gallon tank and gets 10 mpg (I think). 650 mile range seems like more than I would need.
