Great videos Don! I watched them all the day before I went to go take the AT4 for a test drive. Walked into the dealer really feeling like I knew the truck, bought it on the spot after a test drive! Same colour combo but with the 5.3L. Really lovin it!
Also been a while since I’ve seen Sask. since I moved to the US a bunch of years ago. Don’t miss that drive from Edmonton to Winterpeg to see the folks. Keep it up and thanks again.

Love my AT4 - Tows like a Champ ~ Nicely Don Sir

My 2019 At4 with the 6.2 tows my 26 ft travel trailer with ease in the southern Arizona mountains.

Great looking truck! I ordered mine in March but no word on it yet, hoping like hell I get it before the snow flies!

[danmagill]

Hi Don, I always enjoy your videos! I have a Trail Boss, and I’m pretty sure that the AT4 has the same factory lifts. 2 inch in front, 1 inch in rear. ( I also have the Bilstein 5100’s, not sure how much that equates into the equation). What’s the drop on the trailer hitch receiver and which brand did you end up going with? Thanks

Great video, love the drone footage.

I have a 21 AT4 Turbo Diesel Carbon Pro, haven’t trailered anything yet but we have a family boat that I’ll be taking soon.

[jcurry]

Great video! Does your truck have the max tow package option?

[jimmyteter]

I wish the turn signal camera popping up was a setting option for normal driving too.

I can't wait till I can order a 2022..I was considering a 3.oL Duramax but after following your vids I think I'll get the 6.2L. I am concerned about this INSTALLED administration we have in the U.S. ruining our energy policy as gas is ailready a dollar more a gallon since the end of january with more increases to come. Thanks for your excellent content on this channel !

Great job covered everything, would be cool to see acceleration and deceleration for merging and quick stops

[stevef]

It’s none of my business, but I’m just curious - what do you do for a living? I’m liking the videos so far!

[steventrudeau]

Make me want to change my trail boss for at4 just for the cams 🤪

[al-basrawi]

great video, have a question, what is the normal transmission temps while towing? will be towing for the first time this summer and i have a 5000lb boat. my truck is the 21 slt with the 6.2 and max tow package. thanks in advance

[wipatriot]

Still waitin' for you to do that shock upgrade...you won't be sorry...

[rubencastano]

Great vid. Love the truck. On another one of your videos I thought i heard you mention you have a travel trailer. What size is it and hows does your at4 do towing it?

[shanescarlife]

Thanks for the invite... Lol!! What lake were you at?

[robertcaceres]

Dig the Ray-Ban's ... what model are they?. Awesome video

[Bear_]

Would like to know how much was that back drop when hooked up. What's the length of the boat N trailer from hitch to back.
