There is a big difference between towing, and towing comfortably. Had a 2011 Limited towing a 24' Jayco under 6K lbs. Towing was OK, a little squat but put 1000's of miles together including a 4K mile road trip a few years ago. Upgraded to a 2018 Limited for lower mileage vehicle and Ecoboost expecting more power and a better ride. Was never happy afterwards. Plenty of power but not enough back end to tow well...and no good options for suspension upgrade. Talked to probably 10 different mechanics, suppliers, trailer specialists. Upgraded the trailer this year (pre-covid) to a Lance 2375 which has comparable total weight. Still hoping to find a suspension upgrade. As it turns out the Lance has a heavier tongue. Towed it a few 100 miles home from the dealer and knew it wouldn't work. Found a 2008 F250 low mileage Diesel. After just 3 trips I can tell you the difference in the payload and performance on the road is worthwhile. The power of the diesel is awesome too, but not as critical as the payload. If I were buying a trailer to pull with my Expy, I'd insist on hooking it up and taking it for a ride. The dealers (both the car and trailer) will all tell you you have more car than you need....I'd really rather have more than I need. P.S. I still have the Expy. I love it too, just not for towing.
I think this all goes without saying. A truck...especially a 3/4-ton diesel (with solid front & rear axles) is going to tow
anything way better than a half-ton, fullsize SUV with 4-wheel independent suspension. All that being said, if I compare...
1) My old '07 Duramax 3/4-ton | no WDH | 6200# 26' camper | ~650# tongue-weight
2) My new '19 Limited with HD towing | with Husky WDH (800-1000# bars) | 6200# 26' camper | ~650# tongue-weight
...the Expy tows it better. I credit a meticulously setup WDH for much of that. I think my Duramax would have been the superior tow rig if I'd had used a WDH with that setup too. Nevertheless, I've been very comfortable behind the wheel of my Expy towing our camper. It's only been once ...but we braved some of the toughest conditions (I-17 in AZ), in some of the most annoying winds I've ever had ...just kept swirling into always being a 10-2 o'clock 30-40mph wind ...
and ambient temps were some of the hottest we've had so far this summer. While I had (and still have) some concerns about the trans fluid temps that I saw (it never got out of spec...but close), I would tow anything under 7500# with a great big smile on my face. I was quite comfortable and can't think of a time that I felt as confident behind the wheel towing something significant (with what is essentially a "big car").
Keep in mind, I've been towing things since before I even got my full driver's license (mostly campers and boats ...but some enclosed trailers and horse trailers too), and I am
sincerely impressed with the control, comfort, and ease with which I was able to tow my camper. Again, I give a
lot of credit to the hours I spent getting the WDH just perfect, but I have zero complaints. My only real regret in selling my Duramax is the lost cargo space; however, the family (6 of us) is much happier not being shoulder-to-shoulder ...and the dogs are happy they get to come now too.
(BTW - the Lance 2445 is on my list. It'll be our next coach, barring financial disaster.)
