So I have a 2017 RAM 2500 G56 with a leveling kit with new 35s 12.5 18 Ridge Grapplers.

Recently deleted with DRD and a 4 inch straight pipe.

EGR is still intact even though I have a eBay kit to remove it.

I've just been lazy.

Anywho I have a roughly 3500# travel trailer and maybe 800# added in the bed.

I recently pulled it to oregon about 6 hours away.

I felt with that light of a trailer and a few extras I should be getting 14 mpg or so, but I'm down in the 9 to 11 mpg range.

Does this seem normal? Or is something I'm missing?

I get wind and hills don't help and I will add I still have stock clutch that will need to be changed soon as I've went up some hills and felt it slip.

I feel like I have to baby it through the gears, so it doesn't slip when I give it power.

Anywho back to mpg. Is that good or bad without any load I get about 18 to 20 on highway.

Thank you all for any input this it my first diesel so I came to the noob questions LOL.
