trying to find an at4 around my parts but having a tough time. I'm looking for one with 5.3 to save at the pump some, but I may have to spring for the 6.2? I'm a little cheap and not sure how I feel about spending on premium especially when prices go back up.

You'll have better resale with the 6.2 and a better trans. 93 is usually 60-70 cents over 87, it's not difficult to determine how much extra you'll spend when you have an idea of expected annual mileage.

Fuel economy difference between the engines is negligible due to transmission

Are they ever going to go back up? They shouldn't unless there's major conflict in the ME or the US decides to do away with foreign oil.

Gasoline prices will rebound once folks start driving again, whenever that is. Refiners like cheap oil.

I'm going to throw on some 275/65/20 tomorrow. I'll report back on fit.

Proud to say I'm now an owner of a 6.2 AT4. Drove it home today. Damn it's tough not hauling ass in it.

New tires are all good. No issues with this size. Goes up from a 33" tire from the factory to a 34.2" tire. Definitely fills it out better and I like the more aggressive look without going over the top.

Picking up my 2020 AT4 3500 on Thursday or Friday! Dealership is installing 40 gallon transfer tank along with airbags and my gooseneck on it


What's that cost? 90k?!

Did you look at 285/60? I'm debating between that and the 275/65.

I did, but I wanted the raised white lettering on this tire which is why I went 275/65 as it wasn't available on any of the 60s. I'm pleased with how it looks. The 285/60 would be slightly smaller diameter so you're fine there and the width you're adding looks to be fine. People on the forums have crammed some slightly larger than mine in there with luck i.e. 35s, but it just looks like too tight of squeeze to me unless you want to put a leveling kit on it. Some say you have to trim and some not.

I paid 74k out the door and ended up going with 85 gallon transfer tank instead of 40. I've been loving this truck so far! I've got a TSD RV fuel card and have been paying around 1.20-1.40 on diesel for last 3 months so it's also been super cheap to drive

Looks very good. I'll be interested to see how you like those tires. Those will be one of the few I'll consider.

I put 600 miles on them this past weekend. Overall ride quality felt about the same. They do weigh about 19lbs more per tire than the factory ones so MPG was down about 1 mile per gallon. Those bridestones were lite to me for this truck. They look a bit more aggressive in person vs those photos as you can see the depth of the tread in person. Overall all good
