Fuel usage 2005 Fleetwood Discovery 39S 330 Cat

Just began travelling in a Discovery and finally took a leg of the journey without running the genny so I could calculate fuel consumption. I wonder how mine compares at 6.4 MPG? It's a 330 HP Cat with an Allison Tranny.

Thanks! Safe journeys!

Would need a little more info such as - what speed were you traveling at and did you have a tow vehicle. ect.
I have a 40' Tiffin w/ 330 cat / 3000 Allison. - I try to run about 63 to 64 mph w/ or w/o a toad and get between 7.2 & 8.6.
Hope this helps a little.

I have a 2002 Windsor 38 PKD, it has the full steel cage construction and is heavy. Last year I averaged 7.5 mpg pulling a Jeep Grand Cherokee. If it's hot we run the generator so we can use the front AC.

In 2009 we went to Alaska, no toad, drove +14K miles and averaged 8.7 mpg including generator usage. We boondocked about 1/2 the time.

I've done a little over 20K miles in the past three years, virtually all with a toad, and the bulk of it on Interstate or US highways. Traveling, I'm moving just at 35K Lbs, and I cruise at 1700 RPM, (which gives me 63-65 or so). I deduct generator fuel before calculating. I've averaged 7.4 mpg for the entire time.

I had a National Tradewinds with the 3126 300HP Cat. It averaged 9.5 pulling a Jeep GC. One trip I saw 12MPG.

Sure I could do that now.

I've many thousands of miles on mine and the life time average is 7.8 not adjusted for generator usage. That's all around the USA (& Alaska) and Canada, mountains, valleys flatlands, summer, winter, etc. Most of the time towing and speeds rarely above 62 mph. Sometimes a tank full will calculate out at 9.1 and sometimes at 6.8 but as I said the overall fuel average is 7.8.
