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!
