Un-Hitching
1). Chock The tires
2). Drop tailgate
3). Disconnect safety breakaway wire
4). Disconnect cable from trailer lights to truck
5). Lower front legs down 1/2 way or more way using electric switch. The less you have the extensions out, the less wiggle you'll have.
6. Lower the rest of the front legs by pulling pins and letting drop to floor. Put something under the landing legs, to keep them from sinking. The thicker, the better - reduces wabble
7). Insert pins back into legs
8). Raise front of RV to take pressure off pin in hitch
9). Pull pin unlocking the hitch handle
10). Release the hitch
11). Pull truck away from camper
12). Get trailer roughly level fore and aft
13). Drop rear legs to about 1 -2 " from ground and insert pin
14). Level trailer - Use Self Leveler
How does this look?
