I'm looking at a new 29 ft Class C with the 6.0 Chevy. I'm looking for real world MPG with this Chassis. I know how you drive effects MPG and RV's are not a cheap form of transportation. I have a Sprinter Class C now and I need something bigger and a Diesel pusher is out of the budget.

Mine (23' on 3500 chassis) is a little small for a good comparison, but we get 10-11 at 65 MPH in benign conditions. Allegedly, the Chevies get a little better than the Ford V10's. Personally I think you should not expect better than 8 MPG with a bigger 4500 C. I'll be interested to see the replies from people who have them.Which Sprinter did you find to be too small?

I have a 6.0 Chevy on a 28 Ft Tioga and ,I just returned from 2 weeks and 1700 miles of trouble free camping averaging 9.6 MPGAt normal Hwy speeds of 55 to 65 up and back on 101 Hwy in California. It is not flat there are hills and valleys a varied terrain. It is the typical brick Class C unlike Snowman's Class B+ that is lighter and WAY more aerodynamic. :)It can be seen in my profile.

I have an 07 28A (29' 9" total length) on the Chevy 4500 with a 6.0L. I normally get around 8.5 mpg's when going 65 on flat roads around Texas. I did manager to get 10 mpg's once, but that was with the generator off, no wind, and all tanks empty. When it's really windy and I am running the generator to power the house A/C, I get around 8.0mpg. I have a Scan Gauge plugged in at all times so I can see how much of a difference my speed makes while I drive. It has probably paid for itself that way.

I forgot to mention: I also sometimes tow a Jeep Wrangler. The 6.0 pulls it very well. My mileage on my last trip was 8.0mpg towing the wrangler and running the generator most of the time while driving 65mph. Towing the Jeep seemed to have about .5mpg impact.

My current long term gas mileage is 8.96 mpg. That is over several years and includes the over the winter gas usage running the genny. Almost all of that has been towing our Subaru. We drive about 60 on interstates but prefer local roads when not in a hurry. It also includes some dry camping but more full hookup, no genny, camping.edit: we don't run the genny while driving.

Which Sprinter did you find to be too small?
