Amazing fuel mileage!
OK, in the old way of thinking my motorhome gets a crappy 7 MPG while towing the CRV.
The CRV weighs roughly 3400 and gets about 26 MPG on a good day.
The motorhome weighs about 25000 + the weight of the CRV for a total of 28400, 8.34 times what the CRV alone weighs.
SO: on a pound for pound basis the motorhome is getting 58 MPG. IE, in order to be as efficient at moving weight down the road the CRV would need to get 58 MPG! The numbers get even more silly using a Prius as the comparison!
Not to mention that it has the aerodynamics of a very large brick!
I don't know about you but with diesel being over $4 a gallon where we live I NEED to think of it this way.

I ride a bus to work these days, saving a ton of $ on fuel. I justify the savings against my motorhome mpg. Factoring that in, I just did a 2,000 mile trip to Yellowstone that was "Free" - paid with the savings of fuel costs over the past year.

8 MPG might not be very good for a car, but 8 MPG is good for a house.

We just purchased a used 89 Ralley Jamboree and are averaging 7 mile per with no tow!?! Is that abnormal too? seems to run good, is it the age or just what to expect?

Never use the criuse control, hold your foot (throttle) steady; up and down moderate hills, never go over 55-60, get the junk out, avoid stop and go traffic, pull no or a light vehicle. Get a Scan Gauge. And you'll get 8-9. I get 9.5 on my 33' pulling a motorcycle.

Cyclone - seems that every time gas mileage becomes the topic of the day, most honest folks will report 7 to 8 MPG as the common number. While I'm sure some guys can squeeze a few more mpg out of a newer tricked out rig, I personally have a hard time believeing anything higher than 8.5. Also, there are a bunch of dudes who wrote the big check and installed banks or equivalent systems. The honest ones on this forum will tell you they certainly got improvements in power, but not MPG. At least, this is my observation over the years.

Normally I see 14 to 16 on the flats towing our Ody on a dolly. We weight about 32,000 and the Ody and dolly another 5,000.

Wish I could do that but the buses don't run after midnight on the routes I need and I don't want to walk 3-4 miles at 1:00 am!!
