The factory jack should have no trouble fitting in the factory jacking location with a fully flat, shredded tire. That is what they are built to do...... change flat tires. Looks like you have lifted the truck substantially with the high lift and the suspension droop is the issue.I recently had a tire self destruct on me. Not enough room to get the bottle jack under axle. Either I could try and dig a hole for the jack in the rocks or I could use the hi lift to get the truck up high enough to get the bottle jack under the axle. The hi lift was much easier.
so you carry the factory jack plus a 40 pound hi lift plus the lift mate........ obviously GVWR is not an issueI don't lift the vehicle body as it would leave the tire on the ground. I use a lift mate hooked into the wheel to lift it and then put a screw jack under the axle.
I've been testing with it for a few months now. I think I am on version 3.5 of the foot. Overall, I really couldn't be happier with the concept. There are still little tweaks and mods to be made for other features, but overall it works great for doing lots of different things. I've been a mechanical bottle jack guy for years ( like a Toyota or Ford factory screw drive jacks ), I think this might be better for a lot of things. In general, I think there are two different camps when it comes to vehicle jacks. One would be jacks that go 'under' the vehicle, typically used for repairs more than recovery. Two being jacks that allow you to work 'around' the vehicle, typically used more for recovery than repairs. It is really challenging to have a jack that will do both very well, and you usually end up with a lot of compromises. In the end, people use what they like and are use to. It's really difficult to get people to change what camp they are in unless they carry both. Personally, I make it a priority to keep trying new things and revisiting concepts to continue learning and developing new ideas.Curious to see what you think after using it a bit.
