MR CARTOOL M85 Car Inclinometer GPS Speedometer Roll Angle & Pitch Angle with Compass Display for All Off-Road Vehicles

essential for parking the RV correctly in addition to other important information about the vehicle

Why did you pick this product vs others?:Complete piece of garbage, tiny screen, cant read it, too dark and not even a real button, so.e cheap plastic wheel you spin. Save your money, this thing is garbage. Ckrd is like 2 feet long. Complete trash waste of money.

the device does not have a holder

This works really well easy to set up and use!

The device uses acceleration and movement to display the roll or tilt. When making a hard turn, the device perceives a roll/lean, but in actuality, there is no roll. The same thing happens on hard acceleration and hard braking. It displays a simplified calculated g-load as a tilt or lean/roll.It’s not useful for actual driving and lean angle determination in the real world.I ended up sending it back.

Installed in deep wrangler.

Bought in September. Installed shortly after. Worked great for a while then just quit. No display. Went to check warranty and the website is not good

We do a lot of traveling in our RV with off-road excursions at the stops we make, so this is a very handy device to have with us. I like size of the device, and the display is very easy to read. Also, it is simple to change display modes. In addition, I like all of the data that can be displayed including the roll and pitch angles for off-road use. I also like the GPS functionality and data display that shows the current speed, altitude, distance traveled, etc. This is definitely a very useful device that functions well for my purposes, so it earns my five star blessing and recommendation for sure!
