I only purchased this 5 weeks ago and it is winter. So I can't tell you a lot. It has power for 6.0L. I purchased the 2500 instead of 1500, because I just bought a 37' 5th wheel, which I will not be able to for 3 months or that warm weather arrives. So the gas mileage is only 12.3 right now. The ride is pretty sift. Lacks inside floor storage need to add plastic under rear seat storage. Don't like the fake ram air on hood.
acceleration, the solid feel, heated seats,
I wish they would have added a rear sliding window, outside rear view mirrors that were powered instead of manual so you could drive into garage.
You plan on towing a 37' 5th wheel with a 6.0L Gas engine? That poor engine is going to be getting an extreme workout. Should've gone with a diesel bro. Anything under 30' you can probably get away with a 6.0L if you're not towing all the time, but rule of thumb, 30' and above its just more logical to go with a diesel.
