Which gets better fuel mileage, a dually or a SRW

A friend told me what he was getting on his dually and my SRW was doing better, fuel mileage. Pulling different campers

Dually will get worse, but the difference is so small you probably could not calculate it. It all boils down to how much weight your towing. RVing has very little to with fuel economy and more to do with enjoying your RV experience.

Agree with the previous post.

Tune will make a difference. So will deletes. Difference between SRW and Dually is minimal.

For me, I'll take the added stability with the Dually.

I really didn’t know, I have deleted the emissions on my truck but I was still beating my friend by two miles to the gallon before the delete. Now of course it’s three miles more to the gallon

Worrying about getting better mileage when you’re RV-ing is like trying to see if there’s a way to get more people safely on a motorcycle.

Kind of a lost cause.

Some of them do. Some of them don't. Some of them are black. Some are red. Most are white.

The rest are all alike.

I would be more concerned about being attacked by a herd of wingless chickens after leaving a Buffalo Wild Wing Resteraunt.

But for some, the truck could be their daily driver and any increase in mileage is appreciated.

Fuel mileage is considerably close to both. Payload is not, and auxiliary fuel tanks (now that I have one, it's a MUST!!! It's a #1 item), stability, overall payload, is way more important than a probable .038928 mpg.

My friend probably has a different rear end than my truck. He said he was getting about 15 around town and I’m getting close to twenty. And his is a Ford and I have a Silverado
