Someone at the Oregon Gathering acouple of years ago...hummm who was it
At any rate, told me this is what they did: Level the trailer front to back and side to side by placing a round bubble level inside the freezer compartment. When it's
perfectly level, stick a "bullet" level at the front of the trailer (just under the belly band) and another level just front of the door...their front tongue jack was on the door side. Easy to check both while unhooking and leveling. Once that's done it's easy to level every time. Appears that's the same advice given by Mike Taylor...
