I also had a similar experience. Went camping about 2 weeks ago with the inlaws. The father in law owns a 2007 dmax and pulls a 33' jayco. He was disappointed that I bought a 6 cyl for pulling a tt. He says I should have at least bought a v-8. Just doesn't understand that this v-6 has more power for hauling heavy loads. Anyways we went on a 300 mile each way camping trip and he led. I followed with my 8500lb 31' tt. He didn't want to admit it but I could tell he was trying to pull away from me on every on ramp we took. And this little ecoboost kept right up no problem. I dont know how hard he was in the throttle but it would smoke pretty good and is completely stock. I didn't have to floor it once but did get on it. I know I was impressed.
