I recently purchased a 2018 Bighorn 3160 El. I'm trying to figure things out a bit and I have come to realize there is no jack or tire iron to change a flat tire. No procedure in any manual I can find. So here are my questions. Can I use the 6 point leveling system to lift one side of the trailer off the ground without damaging the system? Is there a published procedure for lowering the spare and or changing the tire? Any other ideas to safely manage this process?
