Just an observation but Rick is correct about a 3-4 liter V6, modern ones can turn 6500 rpm and be making 90% of the torque peak there. Able to drop a gear lower than a V8 or Diesel makes up for a lot of the apparent power difference.

ps if you work at it a new 2WD Grand Cherokee Laredo with V6 and towing package can be had for a touch under $30k. With the older 5-speed I get 22-24 mpg on the Interstate, 19 around town, and 17-18 towing the TM @ 65ish.

Just for comparison, a full size truck pulling a conventional travel trailer only gets about 9 miles to the gallon. The TM excels in getting great mpg . You are not pulling a parachute down the road like you are with a travel trailer. I tow with a 5.7 v-8. I get about 14 mpg towing.

Default Chevy 5.3L V8?

Can we hear from the Chevy/GMC owners that have the 5.3L V8
and in the years 2014 and newer? What is your MPG pulling a TM?
The recent engine upgrades include 'AFM'(Active Fuel management),
'VVT'(variable valve timing) and direct injection for best power, torque and
fuel efficiency.

Thinking of changing my TV.

Recently got 14 mpg towing a 3023 on mostly flat ground in MN at 65 with a 2018 Honda Ridgeline RTE.

Default And now for something completely different

I bought a 2017 Hyundai Santa Fe new a couple of years ago. This is the full size 3 row seating unit, not the 2 row Santa Fe Sport. I chose it because of the purported power, reliability, warranty and value. Seats 7, 3.3L V6, 6 speed. Lots of power, especially when pushed in the "sport" mode. 5,000 lbs towing. I like it alot. I added the Curt Class 3 hitch, trailer wiring, DC power, braking and 7 pin trailer connector myself. We live in the Sierra Nevada foothills and a week ago travelled to Hemet, CA, NE of San Diego to pick up a new to us 2014 2922KB, a 9.5 hr drive. By the time we inspected the unit and bought it the next morning and set up the WDH, etc. it was 11am and 100F. Heading NE to take the Mohave/Barstow route we hit peak air temps of 116F through San Bernardino. Over the Tehachapi's it was 114F and we kept the pace, falling once to 50mph, only out of caution. If the temp was lower, I'd have pushed it harder. The temperature gauge never budged off of it's regular reading the entire trip. I know that doesn't mean the ATF wasn't too hot, but it is a good indication that temp was being managed.

We got 16.7mpg on the trip home, including the mountain passes and pulling I-80 on the way to Grass Valley. This was in very high heat over 100F almost the whole way, AC running and pretty much maintaining the truck/RV pace on the CA-99 of 63mph. Trans almost always in 6th with the torque converter locked at that speed. On another trip, we recently got 25mpg with no trailer, a full load of people and luggage running AC. I am happy with these efficiencies. The Santa Fe is a VERY quiet vehicle, which made the trip just so much easier.

The Toyotas are certainly an excellent choice, but to me the premium price isn't worth it. This was just one trip, but I am very pleased with the results with the Santa Fe.

We pulled our 2720 from Vancouver BC to Seattle this spring. Mileage is heavily dependent on hills, but I'd say it was in the 17-19 l/100km range. I suppose AFM does better, but a lot of people disable the AFM due to lifter failures causing engine damage.

I'm quite interested in Fords with the new Ecotech motors. The older ones had one set of fuel injectors directly into the cylinders. Consequently, the intake valves would foul up. The never ones have two sets of injectors, one set to keep the valves clean.

Iím eyeballing a Ram 1500 EcoDiesel. High 20s MPG sounds superb to me, I figure that would translate to low 20s while towing.

I donít think Active Fuel Management would kick in much, if at all, while towing... Especially if youíre in Tow/Haul mode.

Oh, I was thinking Canadian...
Should have been 17-19 L/100 km, which roughly translates into 13 -14 mpg.

They could never match the eco - engines, but are easy and cheap to fix.

Interesting, my 6 year old Jeep returns 17-18mpg of 87 PON at 65 mph pulling the 2720SL. Would think a 3.5 ecoboost would do better.

Big thing is to keep it below about 40% throttle, much more and you get into Power Enrichment.
