Sunseeker 3050SF - 5.7 mpg. Help!

Ok, I just filled my tank and found out my gas mileage was 5.7 miles per gallon!

I'm new to motorhomes, so could some of you wonderful folks please provide me some advice as to how I can get that number up a little more? I'd really appreciate it.

What gas mileage are other folks getting out of there ford class C motorhome?

We just made a round trip from central Missouri to Colorado Springs, CO. We towed a 2013 Ford Focus(4100 lbs) behind our 2014 Forester 3051S. Our mileage was 7.15 mpg going out and 8.08 mpg coming back. We averaged 63-65 mph and had dash a/c on -- did not run generator. This is typical mpg for our unit.

Seems a bit low unless your trip was mostly hills and short. I wouldn't worry unless you check it over at least a thousand miles and a couple fill ups. You should get 8 to 9 MPG. I have a 3120 which is normally about 8.5 with 4K toad and a little over 9 without. The 3050 is a heavier floorplan but it shouldn't impact mpg much.
As for driving style you can save fuel by not driving it to maintain the speed limit no matter what on hills. Back off a little to maintain higher gears and lower RPM and you may slow down 5 miles or so but save fuel. Speed control will eat fuel as it will shift down to maintain speed and often let the engine scream at 4-5 thousand rpm. Sounds good but not good for mpg. Speed control on slight grades and level is fine.

2011 3170DS +-8mpg. That's with cruise set to 62mph freeway traffic.

Heavy head wind, generator running, & or faster speed... 7-6mpg is to be expected.

What was your driving variables?

Also remember you can't base it off one fill up to the next. We have long units and gas islands are not all level.

There has been many times I knew the tank should of taken more fuel than I could get into it.

Just last month I had a full up in the 5mpg range, but I had ran the generator 8+ hours in a parking lot (0mph) and it had also ran the whole time the ignition was on that tank.

Thanks guys. That's exactly what I was looking for. I do use the speed control and went to Mystic CT which was a mostly interstate ride, with some hills.

If anyone has any other tips on saving gas I'd appreciate it. I'll go ahead and look up the other post as well. Always forget to do that.

Since you made it sound like it's the 1st tank, there really not much to base your mpg numbers on. If after the 3rd fill it remains that poor, make a visit to a Ford shop for Dyno testing, that is not acceptable mileage for that engine/chassis.
