Cooper Discoverer All Terrain is what I run on my Ram 2500. Great looking tire and a set of 4 was 660 plus like $18 per tire install at Walmart.
The Cooper Discoverer AT3 was on my '06 2500 (before I sold it) and they were great. Rotations at 10k and lots of traction, but also really good life. Great in the snow and mud.
The Toyo Open Country AT are what are on my '08 3500. Solid tire, definitely needs rotations at 10k, lots of traction with fantastic life. Not anywhere as good in the mud as the Discoverer, but in the snow they were about 85% of what the Cooper tires would do.
New tires are Cooper Discoverer Stronghold AT 285/75R17, which have a 129 load rating (4,080lbs) and only weigh 56lbs. They are 11.2” wide so hopefully don’t rub like the BFG’s (will be installed next week), and weighing 10lbs less per tire is a big difference which will help the MPG. And a 60k mile warranty is nice.
Toyo m-55’s best fucking tire on a diesel truck hands down
Always go AT tires, they provide the best of all worlds, especially when you don't take the vehicle off road. I swear by Cooper Discoverer AT3 XLT's and BFG T/A KO3's
Get the Toyo RT trails. They ride smooth and are more than quiet enough for me. Lighter than MT, look cooler than the ridge grapplers, more aggressive side lug, heavier load rating than Mickey Thompson for 35x12.5
Toyo open country . Surprisingly quite and smooth and great on and off road within reason.
I ran an F Toyo MT in the same size on a '17 Duramax SRW. My camper is MUCH heavier than your popup so my tire life was in the 30k km range. I wouldnt say the Toyos held up much better than the tires that are 1/3rs the price, but they are a durable and refined product. Ive burned through a half dozen sets of Toyo MT and never had an issue with them.
i had these tires on thru the previous two winters. i put them back on for this winter and the performance is severely diminished. they have about 16k miles on them. i won't buy them again.
I absolutely despised Cooper Discoverer tires. I had two sets on my Frontier and they kept feathering. I had no issues with alignment, suspension or air pressure. I eventually switched to cheap Starfire Solaris HT and they were great. Tire issues gone
