And welcome to the forum!
Couple other things, if the trailer has leaf spring suspension, the weight on the wheels will equalize. If it has torsion axles, it will not, to any great extent. I prefer keeping torsion axles relatively equal in load, even during storage. But not end of the world. Although it could sack out the rear torsion spring over time.
Also, know how "level" it needs to be. It doesn't need to be perfect. Absorption fridges work fine a few degrees out of level (look it up it's different based on front to back of fridge vs side to side. But the max for one direction is (the lower amount) is generally 3 degrees (6%) which is alot. When it comes to how much you have to level it, it will be a significant difference. Do the math and see.
