I tow the 28dsbh with a Tahoe that has less than your truck capacity and I pull it with full tank of fresh water and it does fine. My neighbor just bought the same camper with the f 150 v8 and 342 gears and he has no problems pulling it either.

Just watch the tranny temps and take it easy on long climbs and curvy roads. That turbo will scream and "Eat fuel" under heavy acceleration. That milage that ford talks about will be just a dream when towing and with a lead foot. The Ecoboost gets its power from the turbo. Thats not a bad thing, but when its spinning, its packing in the gas to feed those little cubic inches.

Love my Duramax that pretty much climbs anything with pavement and rarely will it ever exceed 3000 rpm's. For sure it sucks fuel under heavy power, but its just humming not screaming.

Vapor Locked?

X2 with Bassdogs on this. Watch that temp gauge.

As a newbie, also don't push your speeds. There have been many threads on the forum asking folks what speed they pull at and what their TT tires are rated for. Most agree the 55-65 as a maximum is safest.

We have a YUKON XL and are pretty maxed out on our tow rating with our Jayflight 26 BHS. Here is an experience I haven't read on the forum but may become of some use to you in regard to climbing mountain passes.

We were climbing out of the Santa Cruz beach area headed to Sequoia NP. The ascent traveling to the park entrance for us started below sea level and climbed to 8,000 feet. My tendency was to try and force the transmission to downshift as we climbed by punching the accelerator. Not an effective choice. As we passed the 6,000 foot mark the TV started to chug and stopped in the road. This is a two lane road, no shoulders and a pretty steep incline. I'm blocking traffic on a winding road. The engine acted like it was vapor locked, which since it's fuel injected had me confused. Fortunately a tow truck driver stopped and had me remove the gas cap. Hot summer temps create excessive fumes and indeed create a "vapor lock" type engine chug. Removing the cap to let the fumes escape worked like a charm, engine started right up and purred. Next advice he had for me was to just baby the throttle and let the engine do its job, slow & steady in low gear. We made it with no issues.

Good luck on your new camper. I love the Whitehawk line up. Enjoy!

Before we moved to the Eagle 5th wheel, we towed our Whitehawk 30DSRE with our F150 Eco-Boost (with max-tow package and 3.73 gears). I could not believe how that little thing towed. Since it creates LOTS of torque and horsepower quite low in the RPM range for a gas engine (look at a graph of its torque curve), the little thing never had to get up to any high RPMs to do its job.

Towing up I-77 going out of NC to Fancy Gap, VA, there is an 6 mile climb with a grade of around 4.5%. The rig held its speed with no struggle. On another trip from NC to upstate NY, I intentionally tried some really heavy grades. As an example, instead of going up Rt. 29 to I-64 to cross the Blue Ridge over Afton Mt. (heading to i-81), I cut off and climbed to the Afton Mt crossing at Rockfish Gap using Rt 250, again without any issues.

Regarding the overall length of the rig, finding gas stations on long trips that are accessible to such a long rig was my main concern. Really need to be careful!

Oh, BTW on our long trip from NC to NY and back, we averaged 11 MPG! I was really happy with that.

That's funny Big Sky, I just had the same gas cap issue on a riding lawn mower last week!
I appreciate all the replies. I don't plan on climbing any mountain passes in the near future that's for sure. Most of what I plan on using the camper for will be weekend getaways and possibly one weeks vacation a year. I am a partner in a small business so the type of trips you guys are talking about are something I dream about doing 'some day'. I am mostly leaning toward the White Hawk over a hybrid because it would extend my camping season. I'm concerned about the length, however, because one of my favorite local places to go is the Allegheny Forest. Some of those forest roads can be a little iffy.
