I have posted a video "Up The IKE Gauntlet with 2017 Ridgeline towing 4440lbs "
The weight was higher on the return trip because I did not dump the black and grey tanks. Both 25 gallons and both where 2/3 full. I also had some fresh water in the tank. I really wanted to test it with allot of weight. I did go straight to the CAT scale to get an accurate weight of the Trailer. You will see that at the end of the Video 4440 lbs !
I was impressed with the way the G2 Ridgeline handled the weight up the IKE Gauntlet. It had no problem 60 - 65 mph. Even though I had the pedal to the floor it did not feel like it was struggling. As you will see from the video there was no gear hunting by the new transmission. My only complaint was near the top I wish It had down shifted a little sooner. I think the Ridgeline could have handled the full 5000 lb tow rating at speeds 55-60mph.
The surprise of the trip was the millage. Overall millage on the trip computer was 14.6 mpg. But from my manual calculations it has been about .8mpg high so actual was about 13.8mpg over the 350mile + trip. I had been using ECO on previous camping trips that had fewer hills and passes and less weight, yet it got lower mpgs, with eco on 12mpg. So don't tow with ECO on you will get better mpg.
Enjoy the Video! If you have questions just ask.
EDIT: Forgot to mention IKE run time 7min:35secs well under TFL bench mark of 8min.
