Finally was able to tow with the new truck for the frist time over the weekend, and WOW what a difference compared to my old truck.
I went to pick up our boat (2020 Mastercraft XStar) from winter storage and towed it about 500 miles home. (Long story why we keep it so far away but its worth it).
When dry and no gear we are about 8k on the trailer so its pretty light compared to what my truck can tow. When we load it up with lead, gear, and fuel its about 10k on the trailer. I cant put into words how much better this tows then my Tundra or old Chevy 2500 HD. The power is so linear its insane, you hit the throttle and it just pulls forever. I live in Lake Tahoe so coming from the central valley up Donner Summit was always a chore in my old trucks, not anymore. I was going about 65 the entire way up the pass and could have easily done 80 if I wanted. Just endless power. I got 13 MPGs the entire 500 miles home which includes a ton of climbing so I was happy with that.
The trans/exhaust brake combo is also really aggressive when descending or coming to a stop. Like you tap the brake, truck downshifts twice, exhaust brake hits and you go from 65 to 35 in 5 seconds. Its impressive.
I know there is often a ton of debate on gas vs diesel but I living where I live, there is no way id buy another gasser for any amount of towing. Its well worth the $10k IMO. I forgot to take pics of the boat hooked up to the truck but will post some this weekend when we are out again.
