First “real” tow with the new to us truck in my sig.
Have pulled my 32’ snomachine trailer all over this winter, but not near as large as the new toyhauler.
Interested to see how an under-geared (3.42s), over tired (37” Toyos) truck with a 6” lift would handle a bigger load.
Dropped the new camper on the hitch yesterday. Aired the bags up to 40psi to take the sag out of the @ss end and pointed it west.
From a handling standpoint, 35’ long high profile bumper pull toy hauler was zero issue. Even the typical nasty winds in Eastern WA didn’t really phase it. Got pushed around a little but nothing challenging about keeping it between the lines.
Power wise, I was expecting it to flounder a little maybe. Was running a 90hp tune.
But the truck ran 75-80mph, locked in 5th gear (6th is far too steep for highway speeds towing, with the tall gears and big tires). Engine and trans temp never budged from 200/170 +/- and truck never downshifted except coming up Vantage in the 5% grade stretch, she wouldn’t hold 1800rpms and 70mph in 5th.
Having never had a big tire, poorly geared, lifted diesel before, wasn’t sure how well it would do, comparatively.
But I can say all the blather about how bad lifted trucks are for towing, is really quite overstated.
The big C is a beast!

Nice looking truck! MY mileage suffers if I get near 70 so I tow at about 62 mph

Thanks man!
MY mileage didn't suffer, it was on life support!
Obviously that truck doesn't get great mileage to begin with, but the ride back was about 7mpg!

That's the part that impressed me (not the fuel mileage). Gotta be working the truck pretty hard to get 7mpg and she wasn't really on the boost much on flat ground, even with the wind in my face and the engine and trans temp basically never budged.

I agree with you! The old 8.1L big block and 4 speed trans in the Burb towed our 9k trailer pretty good, I never understood what all the fuss was about diesels.

I haven't been to the scales yet with the camper loaded on, but I suspect we're right at our 12,300 GVWR and that Cummins just hums along.

Only issue I have with the diesel is drive-thrus....the engine noise reflects off the menu board and if you don't SCREAM the kid inside can't make out what you're asking for [emoticon]

When I look at that picture I see a transmission rebuild in your future.

If he keeps it in its power band it will be fine.
