Awesome. Thanks for sharing. I think i will have to drop mine a level lower . As your can see no bars attached and the trailer sits relatively level but i have to raise it considerably higher in order to hock up before i could drop on the ball. I think dropping it down should help with that.
Nice looking setup. Do you have to run a drop hitch receiver? We just bought a 21 Sierra SLT and the center of the receiver sits at about 18", Our other tow vehicle (X5) Has a center point of the receiver at 15". We haven't had a chance to head over to storage yet and see how the new truck levels out with our 23ft Airstream. Hoping i dont have to go the drop hitch route as we use a WDH.
My SLT also has a very clear back up at night in very dark conditions. Believe OP's truck has LED bulbs also?? Either way back up camera on mine is by far the best iv ever had. Much better than our BMW x5
Not Apples to Apples but i did test drive a 2021 Silverado Custom, Sierra SLE and 2021 Sierra SLT. I ended up buying the Sierra SLT for a multitude of reasons vs a lower trim level but i would say overall the sound difference is small. All were powered with the 5.3. My SLT has the Z31 package also which i would say gives a slightly noisier ride due to the tires but if comparing the Custom with the SLE they seemed almost the same to me. I felt my SLT was overall quieter at higher speeds (Freeway) vs the other two. That could also be the fact that i was leaning towards this truck more also. Tires will make a huge difference
