I'm BACK! The Ibuprofen must have helped.

Okay, So I have a driveway that is 378" long (Side 1) and it has an 18" drop (side 2)from the rear to the front of the driveway.

So:
Side 1 = 378"
Side 2 = 18
Angle = 2.7263
Hypotenuse = 378.43

My driveway changed while I was watching it. Now it is 468" long with a drop of 15"

So
Side 1 = 468"
Side 2 = 15"
Angle = 1.8358
the funny name = 468.24

Now, because it was a funny name and I was watching the driveway, it changed again.
It is 264" long and only 12" on the drop.

So:
Side 1 = 264"
Side 2 = 12"
Angle = 2.6026
And that funny name thing called Hypotenuse is now 264.27.

Well, that was what I came up with, and I didn't have to use the refrigerator.

Where (No I couldn't) did I make any mistake.

Sheesh, your driveway sure moves around a lot!

Using the Google search formula I gave above - simplify your life - and you get the following results... No hippopotamus (hypotenuse) required. You are only looking for the degrees, not the length of that triangle's third leg.

Case 1) Google "arctan ( 18 inches / 378 inches ) in degrees" (of course don't enter the quotes)
and Google will answer arctan((18 inches) / (378 inches)) = 2.72631099 degrees

Case 2) Google "arctan ( 15 inches / 468 inches ) in degrees"
and Google will answer arctan((15 inches) / (468 inches)) = 1.83577474 degrees

Case 3) Google "arctan ( 12 inches / 264 inches ) in degrees"
and Google will answer arctan((12 inches) / (264 inches)) = 2.6025622 degrees

Obviously, there is some error in the measurements - holding a level line from which to measure the drop distance is not easy.

However, given the closeness of the angle results from those three measurements, you are WELL WITHIN any reasonable error tolerance.

Your drive is about 2.4 degrees (the average)...

...and the Google "search" to compute that average of your three measurements is "(arctan (18/378) + arctan (15/468) + arctan (12/264)) / 3 in degrees" which Google will answer with 2.38821598 degrees

Isn't Google fun? And it requires a whole lot less ibuprofen.

Does your angle finder have a 'zero' function?

Ha ha! I dropped the refrigerator on the ground, the pushed it. The three different lengths is where it stopped. Pushing it up-hill was the shortest distance, but I put muscle into it.

Obviously, there is some error in the measurements - holding a level line from which to measure the drop distance is not easy.

Nope! No line. Just eyeball with the help of a laser level. Leveled the laser at the back end, took a tape measure to the opposite ends and measured where the dot hit on the tape measure to get the "drop" on it.

However, given the closeness of the angle results from those three measurements, you are WELL WITHIN any reasonable error tolerance.

Your drive is about 2.4 degrees (the average)...

...and the Google "search" to compute that average of your three measurements is "(arctan (18/378) + arctan (15/468) + arctan (12/264)) / 3 in degrees" which Google will answer with 2.38821598 degrees

Yep! Google is nice. However, i'm more sophisticated than a simple Google search. I wanted to see the formula so I used:

click here> Hippo Calculator <click here


I just threw the hippopotamus in there to show ya'll how snart I is.

Yes! When the pointer is straight up it is at "zero."

Couldn't resist! Other than that, no.

Thank all that have responded, even those with the refrigerator theories. It has been an education and I am still dumb in math.

Now that one is easy.. Though for most RV's side to side is fairly standard (8 feet, even a motor home which is 8 1/2 feet wide the wheels are 8 feet) Some are narrower.

But end to end.. Well my motor home is a 38 footer, the front/back wheelbase is closer to 28 feet however. and a DP it's closer to 20 for the same length, and the trailer I traded in on this class a was 13 feet long.

So using "Bumper to bumper" what was 3 inches on that trailer would be closer to nine inches on this motor home.

The maker of the fridge, does NOT KNOW what it will be installed in.


I have a set of stair steps.. I took a 3 foot length of 2x8, on top of it (Near one end) I bolted a 2 foot length of 2x8 and on top of that (also near one end a 1 foot lenngth

1.5 3 or 4.5 inches of "lift"

I have 3 of 'em. on 2 the 1' length is removable.

Never did learn to speak algebra, so I just use the old "block and tackle" method for leveling. I get my blocks out and tackle the job of getting it level. Found that if my slides work properly then everything else will, too. Best thing ever invented was that little water bubble next to my electric levelers. Had to stack four blocks under each front wheel in Mt. View, Arkansas, but MoHo was level. Of course...also had to put blocks under the steps to get in the thing. lol

Sometimes I wish I had replaced the algebra book that was stolen in high school. I got an "A" in geometry.

This is not about leveling the MH, or the refrigerator. It is a math problem that I wanted to learn to determine the angel of something.

So go back and re-read all posts in this thread and substitute refrigerator and Mh with the word "2 x 4"

Works for me.
