You gotta stand on the tailgate to get it up there. That photo is from last summer. The spare is in the bed now. Yeah, tire on steel wheel is heavy, 108 pounds each. It was a pain to rotate tires, even on the driveway. I'd hate to need the spare on the trail. Plus, she's so tall, a tree branch caught the tire and broke one of my rack mounts. Future plans call for a new rear bumper with a swing away tire carrier. The rack will be mounted 3" lower with mounts right on the shell, and no load bars. As far as 37s go, I'd have to put a step on her to get in. She is sits just right now, as she is my only truck, a daily driver. I don't need her to be a pain to get in and out of. My wife already hates riding in the truck. She needs a step stool to get in and out. Plus it would kinda defeat going up as I loose rocker clearance with a step hanging down. Seriously considering sliders though.
