Not sure how two kids and a dog keeps you from having a truck? How big is the dog? Our 40lb mutt rides between two car seats in the back seat of the truck.

Sorry Texas, you are absolutely correct except our mutt gets car sick so must be in his crate. I looked into it because some of the new trucks have designs where they work on less cylinders to save gas when the power is not needed. It would have been a great solution.

During my years of towing, I've learned that PUs (tent trailer) and utility trailers are nicely tucked behind the Tow Vehicle. Thus, they have near zero wind drag. With a TT or HTT and its higher construction "above" the TV's roof height, it will drag (stress) the TV pulling it. Up hills and/or against a strong wind, a much higher trailer often feels like towing something 500 to 1,500 lbs heavier - then its non-moving scale weight. When I towed a 19ft TT behind a Safari van, there were a few times I purposely took the back roads (re: Down HWY 2 instead of wind tunnel 401 ) because certain regions on the 401 hwy are known for bad wind tunnels. But on calm wind days, I took the normal hwy. When traveling "at the weight limits" of the Tow Vehicle, do pick the better road routes. Your smaller sized tow vehicle will thank you.

If wondering, dramatic lower in MPGs is because the Tow Vehicle is struggling too much. re: One presses harder on the gas peddle to keep the same ground speed - which sucks even more fuel. When Towing, a larger size engine often struggles less and math wise, it gets better MPG (when compared to a "too small" of engine that's being over stressed).

Hope this helps in your research....

No doubt, it takes horsepower to pull a TT with large wind area to it, as Spike99 says. This being the case, those new trucks with the fuel saving "run-on-4cylinders" will never switch to that mode when towing the TT. That feature may help a bit though, for times you run the truck around town for day-to-day errands.

I drove from just south of Birmingham, AL to Panama City Beach, FL last Tuesday. The truck and 5er are in my signature. I always drive very conservatively and set the cruise at 55. My hand calculated fuel economy for this trip was 12.8. I always use tow/haul until I am at 55 when I turn it off. This allows an rpm drop of a couple of hundred. I turn tow/haul back on if the transmission starts to downshift on a hill.
I'm sure one reason for my good economy is the 55 haul speed. I'm in no hurry so why burn more fuel?

People will often leave the transmission in to high of a gear and the engine is lugging and working hard to mantain speed even on level ground. Mileage sometimes will improve by running a gear lower and letting the engine run at more RPM's. Your foot is not pressing the go pedal as far down. Nothing hurts fuel mileage more than the foot to the floor and the vehicle not gaining speed.

We have the 2011 Skylark & pull it with the 2011 Honda Ridgeline RTL, our best is 11.8 MPG...I thought we would get better mileage. Honda Ridgeline is only rated to get 15 city and 20 hwy.

We love our Skylark & Ridgeline!
