Side Slope Measuring Device?

[MisterE]

Yeah, I would think that it would be able to go more than 22°. As I said my math sucks that was why I wanted to know how to figure it out but a 40% slope at first I would have figured 90° a 100% side slope and 50% or 45° half, then knock another ten percent off that. I was suprised to hear only 22°.

But as I said my math sucks and I totally defer to you guys as the last thing I would trust to my math would be my H3!

Thanks Guys \ Gals!

The slope % comes from the amount of rise divided by the run.
Example: 1000 ft. rise divided by 3000 ft. run = .60 or 60%

This is the way roads are listed on grade signs.

They use the same method for side slope. 4/10 = .40 or 40%
Calculating the angle gives 21.80 degrees.

The gage must be mounted vertically to be accurate.

Wow, now I am totally lost, when I do it I get 33% for you example for the rise \ run example.

I am guessing the mounting behind the review mirror is a good place so that it reads 0? on level ground.

Sorry for being so dense, like I said I trust the numbers you guys are giving me I just wish I could understand how you get them so I didn't feel so stupid!

It would be 1/3 = .33 or 33%

You could think of it in terms of the width of the H3, about 6 ft.:
2 ft. higher on one side gives 2/6 = .33 or 33% Hope there are no bumps.

The gage that Neo shows appears to be stuck on the windshield at an angle which induces an error.

Is this a good link for the math for our application?

read thru this thread also , lots of good stuff

good rule of thumb;

if the door handle is touching the ground, the slope is too much

Hey All,

I just got the same gage as Neo. If it is stuck at an angle how much error will it induce? I'm looking for the gauge to tell me if I am getting in the danger zone but I'm not going to be staring at it for an exact measurement. Will the angle make it useless or are we talking a degree or two off, which would be fine. As I said I'm just looking for when I've entered the ballpark of being stupid!

I am going to have to defer to the experienced wheelers since my only experience is from growing up driving on washboard roads.

I have been following this useful Forum to learn what the H3 is capable of.

You could check how much error is induced by putting the gage at different angles and see what the difference is between having the gage face verticle and at an angle at which you are planning to mount it. It looks like the gage has a ball for the indication so it won't suffer from friction.

I don't know when one gets to the stupid point but the door handle dragging may be it. If nothing is dragging, I can't see a problem.

Best regards, Happy Jack

The gauge will always be somewhat off unless you're on a side slope thats level front-to-back, so don't obsess over it. Its best to use it as an "oh sh*t" meter to keep out of trouble, i.e., be conservative. The exact max angle isn't a fixed figure; its very much different for a rig with two people and lunch cooler than for a heavily loaded rig with a load on the roof.

If you flop on your side, its an expensive "oh sh*t"; but if you keep rolling down the hill, I guarantee it'll spoil your day.

You have to calibrate the "Tip O Meter" to compensate for any the lean in the truck. This should be done on level ground with equal air pressure in the tires.

They are fun to look at but usually when I'm in a bad side hill spot I forget to check the angle. I like having the side hill and up and down angle too.

Also the rollover angle will change with bumps, soft shocks, roof rack load, soft ground, low air pressure in the tires, blowing a bead or getting a flat on the down hill side. Not good.

do not worrie about not being flat . this has been argued over and over . these are made for sail boats , when sailing the vessel is pitching and yawing at the sametime and it is designed to still give an accurate reading just figure its acurrate to +/_ 5 degrees . you will be fine i know i have tested it to the Max
