Hey all,
So I hooked my '15 5.0 up to a 16' bumper pull stock trailer which was empty and took off down a flat ks interstate. I set it on tow/haul and 5th gear to run 65-70, but the truck struggled with all it's might. I spent most of the 70 mile trip with my foot to the floor board. It would hover around 2100 RPM, and when i shifted down to 4th, it'd soar up to 2800-3000 rpm's just to keep her at 65 mph. the wind really wasn't much of a factor.
I'm concerned, because i used a 2014 5.0 to pull a flatbed and a '51 F3 doing the same speed and it chugged along in 5th with ease.
No warning lights or anything showed up other than the mpg was way down at 10 or lower and our 140 miles to empty fell to 4 miles at the end of our 70 mile trip.... ideas?

An empty 16 foot trailer should weigh less than 2500 pounds, which should not be an issue.
You probably have just one axle, so it wouldn't be too difficult to jack up each wheel and check the brakes for proper adjustment. Just make sure the opposite wheel is chocked and that you place the jack under the leaf spring mounting pad.
The brake shoes should be adjusted out until they just touch the drum, then adjusted in a turn or two so they don't drag.

My 2012 5.0 with 3.31s tows both my heavy assed McKee Craft and car hauler with no stress at all. It doesn't like going up bridge inclines and downshifts to 3rd to be comfortable. Fuel mileage is not too great but we expect that when hauling in a half ton truck. Something is amiss on the OPs vehicle or trailer...OR like mentioned earlier, its locked in "M".

I have a 6 speed 5.4L with 3.73 and it cruises at 1500 - 2000 rpm in the 100km/h range, on level ground. If I put my boot to the mat, she'll go. 3rd gear, 2500 rpm and 130km/h in just a few seconds. To put your foot right down and have no gear or speed changes - even towing - indicates a problem. Not "not enough truck", as whom ever that was had indicated.

I guess I need to clear up my statement for the smucks to see why I said it...
2- 3.5l ---one with 3.31 and the other with the 3.73.....what will tow easier....what will be better getting groceries...

Again, you should stay out of discussions when you have nothing constructive to say with any factual basis.
Differential gear selection has nothing to due with the codes the the trucks is putting up.
The truck in questions does not have an EB it is a 5.0l engine.
An EB with higher gears is still a significant powerhouse towing or hauling, far beyond simply getting groceries.
Finally, the term is "schmuck" not smuck and I think we all know who in this thread fills that spot out nicely

Not clearing up anything other than to show how little you actually know and understand.

Any chance that the trailer brakes were dragging? When you let off the gas did it decelerate more than you expect?
