mpg's whit 3.92's

I have a 2013 6 speed with 3.92's. Don't tow, but average 14-15 in average driving, mostly in town.

If you have a 6-speed, I think you're right in the ballpark, if you have an 8 speed (I can't remember if 3.92 and 8 speed was available in '13), you are probably a bit low.

There should be a sticker on the diff unless it has worn off. I've got 40k on my truck and can still read my sticker............or do a vin lookup

if the window sticker says 3.92, then thats what it has. you can look up your build sheet to verify if you would like. keep in mind theres a lot of factors that can affect mpg's when comparing your average to what you read online.

hello everyone. I have a 2013 ram 1500 express with the tow package.

I have seen a few people on here talk about getting 10 to 13 mpg while towing a trailer, I'm getting around 8 to 10 and down to 5 to 6 going in to the hills. I have a 28ft travel trailer running about 6600lbs. when I bought the truck, sticker and the sales guy said it had the 3.92's. Does this seem right and is the anyway to check the diff without pulling the cover. thanks for the input.

I understand that, but you do know there is a lot of shady dealers out there. My last truck said it had the off-road package shocks, tires paint scheme and lights. It had the stock rims tires, shocks and no fog lights but it did have the fancy paint.
