you’ll have to find a dead level area to calibrate it the first time, (a parking lot?)
The disposable CR2032 coin battery. If you remember to turn it off when you’re done camping the battery lasts a long time.. Bring a small screwdriver and small batteries for longer camping trips.
Sometimes, other bluetooth stuff connected to your phone interferes with the signal between the Levelmate sensor and your phone
you’ll have to find a horizontal spot inside the GFC or your truck to mount the levelmate sensor unit. You can use 3m VHB tape if you don’t have anything to screw it to.
yes worn suspension can require more stacking to get it level because worn shocks can compress more easily, just like when you see vehicles with worn/ leaking shocks they tend to sit lower or lean on one side.
A healthy suspension should not compress that easily to make what you described originally happen. Sure, it will compress a bit, but after that initial compression it will transfer the height gained on stacking to the truck itself, thus leveling it. The only time when your healthy suspension compresses that much is when you have some messed up valving in the shocks that compress way too easily.
Another thing is springs… springs can wear out too, especially if you have stock springs and you have constant weight on them.
only 100k miles doesn’t really mean much when it comes to suspension. it comes down to how heavy you have, how hard you drive, and what type of terrain you usually drive on. If it’s driven hard, hauling much, or driven fast on bumpy terrains (or even if you catch air a handful of times), your suspension will become worn at low mileage. Heck, I blew my Bilstein 5100s on my previous rig with only 30k miles on it, after a few trips to the desert and catching air like less than 10 times (hence after the initial Bilstein 5100s I went King and now on my current truck it’s Fox 2.5… because Kings were backordered with no ETA back in 2022).
