What kind of RPM's do you get? What about MPG?

OP posted the question almost 3 weeks ago and hasnt been back to comment or clarify, so typical “bust” of a thread!

That’s why I covered all the bases in my initial reply .
1500-5000rpms and 6-18mpg.

I have a 1996 F250 diesel with an automatic and 3.55 differential.

At 60mph in overdrive on the flats, I'm at 1500 rpm and can usually depend on 14mpg towing a 27 foot Jayco travel trailer. Things change a bit when geared down in the big hills and on mountain grades.

Just curious what others out there are getting as I look at TT options.

I've heard that 2400RPM and 7.5MPG is pretty standard. Is it wrong?

MPG and RPM is totally dependent on:
Which truck
Which gear Ratio said truck has
Which engine said truck has
Which transmission said truck has
How heavy the trailer is.

There are far too many variables at play to give an an answer.

My Duramax with the 6 speed Ally, I typically am at 1700-1900 RPM.
12 mpg.

Towing a 4K# TT with my V6 2008 Explorer, I averaged 9.5 MPG trying to maintain interstate speeds. Gain between one to two MPG on the back roads from less wind resistance.
Towing same trailer with my V8 2019 F150, I gained about one full MPG.
Both have factory tow packages.
From my earlier research on the RV forums, 9-9.5 MPH is most common with gas engines if towing around 80% of your tow rating.
RPMs? I do what I have to do with the TV engine to maintain headway and speeds.

With our recently traded in 5th wheel at approximately 10000# driving at 65mph, 2200rpm I can nurse roughly 8 mpg. This new 5th wheel will be probably 500-800# less so our mileage should jump up a lot??????.

Most older small blocks...but newer small blocks not so...and big blocks can't, mass plays

My big block cruises & Tows at 1,400 RPM, which is at 100% rated torque,which is where max torque starts and stay flat till about 3,200 RPM

If people with gas engines are towing at 1,900 rpms or 2,000 they are lugging their engines in my opinion.

Yes and Yes

If people with gas engines are towing at 1,900 rpms or 2,000 they are lugging their engines in my opinion.

The idea of 1,700 or 1,400 rpms makes even less sense if you want your engine to last.
