We LOVE the HP and torque of our 2019 MB engine! We can actually HEAR the stereo (as compared to other V10 gas engines that we tried). We live in BC so lots of mountain roads to go up and down without a roaring engine. Now, we only have about 100lbs on our hitch with a bike/cargo rack. Maybe it would be different hauling 5k lbs on the back.....
If you’d like something in between a class B and a class CE 450, the sprinter is the way to go. However, that’s only if you do not carry a lot of cargo or people with you And you don’t mind having a small fuel tank. It’s a niche, one that I traded in for all the reasons I just mentioned.
