I bought my '12 SuperCrew Lariat a year ago. It's gonna need tires before fall.

I have a Lance 8.5 Cabover Camper (2000 lbs) that I keep on there maybe 35% of the time for fishing, hunting, camping, etc. I have a boat, a Jeep, quads.

There's a guy selling some Pro Comp Extreme MT2's on my local 4x4 FB group, and I think I can steal them. I HAVE A LEVELING KIT, and I apologize, I'll have to go look, but I think it's about 3-4" lift in front, and I am embarassed, but I don't remember the rear. I may have some blocks, but can't remember.

My question is: Will I be okay with my cabover on 37's?? I'm running 285 x 65 x 20's now on aftermarket 8" MB Wheels. Both wheels and tires came on the truck. I think 285 x 65 is about a 34" tire, so I'd be about 3" higher. That really doesn't bother me because I used to stick 4x4's under the camper to keep it off the truck cab roof, now I just use a piece of carpet so it doesn't rub. Can I run these 37's???
