The LR4 is amazing off-road. I finally took it out of the city after buying it in July and doing a lot of work to it to address known issues. I appreciate everyone's help here because I couldn't have done it without the community.
I found a dirt bike trail to take it on with a full load of gear. All my overland stuff was packed in there with everything from a 100 pound tent to computer gear. On the freeway I had to give it a lot more throttle to maintain speed, yet if I held the throttle down it had plenty of power to pass and my god this thing is a beast! It drives with a small footprint and it was easy to navigate through the bush although I needed to hack quite a few down and eventually came to the point where the effort to bushwhack wasn't worth the expense lol.
The first hill is hard to hike up on foot because its loose rock (and hard to see from the pic) and I switched DSC off, dropped down to first in Sport mode and it went up without any slip at all, way more than enough power and both center and rear diff went fully locked. I love the LR4 so very much. I can't wait for a need to drop down to 4LO. Watching the dynamic differential locking on the screen is a lot of fun. The ground clearance is awesome too. I was able to flip a u-turn with deep ruts and never lose traction or bottom out. It was a lot of fun coming from a car.
The air suspension adds a massive feature in comfort and capability. I had a whole lot of weight back there with 15 gal of fuel, 18 gal of water and the ass end never sagged. Ever. I noticed that the compressor ran a lot more while in lifted mode so I put it in normal height after finishing the offroad adventure so that I don't wear it out.
I'm also noticing the battery drain at my campsite and at 12.2V or so I started the engine since I'm not sure how many volts it needs as a minimum to start. I tried the Battery Tender Jr and it didn't do much. I'm realizing 800a is more like 12hr or overnight requirement where I want to keep the charge topped in as much time as like what starting the engine does, but I don't want to run the engine every day.
