Levelling Measured At The Wheels; Conclusions; Levelling Measured At The Countertop - Norcold N300.3 Manual

Let's first take a look at the wheels and visualize the variation from level that would still allow
the refrigerator to operate properly.

Conclusions:

1. The TrailManor trailer can out of level side-to-side (wheel-to-wheel) by as much as 9.5 inches
without exceeding the refrigerator spec of 6 degrees. In other words, one wheel can be 9.5 inches
higher than the other.
2. The TrailManor trailer can be out of level front-to-back (wheels to tongue jack) by as much as
7.5 inches without exceeding the refrigerator spec of 3 degrees. In other words, the tongue can be
above or below the wheels by as much as 7.5 inches.
Levelling Measured on the Countertop:
All you need is a 24" long level easily obtained at any hardware store for under $10. I chose the
24" length because it will provide you a measurable variance that you can easily see. And it will
easily store in the nearby overhead cabinets. The use of any shorter level means that an error in
measuring of 1/16" can easily translate into one full inch at the wheels.
Here's how to determine you vehicle's level from inside the vehicle. Stand facing the front of
your refrigerator and place the 24" long level on the flat counter above the refrigerator. You will
need to check straight forward and sideways. It's as easy as 1-2-3:
1. Lift one end of the level until the bubble is centered.
2. Measure how far you had to raise that one end of the level.
3. Compare that measurement to these sketches.
