My RV weighs about the same empty; 3600lbs'ish. Previously towed it with my 2016 EcoBoost Expedition. While the Expedition seemingly had no issue towing it on the surface there was something else going on. After having it awhile, and putting miles on it I began to notice blow-by. While I was impressed with the power, ride, and usability of the SUV, the twin-turbo features started showing their weak points.
Now I know this isn't a Hurricane motor, but there are some similarities in what I'll refer to as common failure points. For example, you have a small displacement engine taking the place of a larger motor. This motor is expected to pull the weight of the truck, and anything it hauls/ tows. To make this motor do its job air is shoved into its already compromised systems; this can lead to blow-by after the truck gets some use put on it as the piston rings wear. I say compromised based on what we know a diesel motor is capable of with its heavy-duty components.
Not here to beat up on the Hurricane trucks, just speaking on my experience with twin-turbos. I went running back to a normally aspirated V8. Hopefully the Hurricane does not run into the EcoBoost issues after they get some miles on them.
I know I've probably got a couple of you guys upset... not my intention at all. Just giving my experience with forced induction. Also, the Ram tows the RV effortlessly as well. Also, notice I did not mention if one had more power than the other... that's because it was about the same in my opinion. The Hemi's power is right there when you need it. The twin-turbo power has to spool first. Guess it just depends on what you want/ prefer in the end.
