Please list your model and fuel economy
Greeting all,
I think my first post was overly complex.
Can you just post your model motorhome and your highway fuel mileage?
Thanks in advance,
Benjamin

2003 XL-396, 330HP Cat
We get 9.2 mpg towing Jeep Liberty 4x4 at 62-65 mph. Better than 10 at 60 mph. Less in mountainous terrain or winding roads since the Allison won't upshift to 6th gear until 57 mph. Using cruise control helps with the downshift points since it will sense "loading" and drop a gear.

93 land yacht moho. i actually have never checked. i bought it to drive. i truly believe that leaving it in the driveway to save gas is the most costly thing i can do to it. you can afford it or you cant and mileage has absolutely nothing to do with it.

We just bought our 95 Classic 360 Diesel pusher about 2 months ago and have driven it colse to 4500 miles. We are getting about 13 mpg. I've seen as high as 13.7 with a bit of tail wind to 11.8 beating into the wind. We cruise about 65 and drive it like diesel is $4 a gallon. I've very pleased with the milage and was only expecting about 10.

We get 15, up/down with our Isuzu, burns no oil at 248 thousand. What happened to your bullet-proof engine to cause a replacement? AND, I guess, the other question would be, was the change-out a big deal and did it bolt-up to the GMC 470 trans? Do you still have the Isuzu engine?

I got the whole Truck. I cut the motor mount off the frame and used them to mount the engine. It was a hard job, but we got it done. It run about 8 to 9 weeks to do the job. It's not a old man job!!!!!

If I had found a wrecked Dodge Commins 5.9L or Isuzu N series 5.2L I'd be pumping diesel in the Silver Bullet now. But none were to be found last year when my 545 Allison transmission went out, so I have a 4L80e w/overdrive. Get the same with the toad as the Allison (6.3), but it looks like I got 7.2 w/o the toad. With the Allison I got 6-6.5 towing or not, 55mph or 70mph. The 0.75 final gear makes for a lot less engine noise.
Now maybe it's time for that hydraulic roller cam.
