[VAL] Fridge unlevel before departure?

["Tom Williams" <tcwilliams@xxxxxxxxxxx>]

When I pre-cool my Dometic refrigerator at home in the driveway before a 
trip, I have to have my Overlander unhitched to level it as my driveway is 
sloped left-to-right & forward-to-aft.  When we are ready to hit the road, 
I then just rehitch it and go.  Lately, though, there has been an 
increasing amount of time between being ready to go, and actually pulling 
out of the driveway.

Short of putting my tow vehicle on blocks, I am unaware of a means of 
leveling the Overlander without unhitching.

I'm curious about how long I can safely run the refrigerator when it is 
sitting off-level in the driveway.  Are we talking an hour, a half-day or 
what?  Keep in mind I plan to pre-cool while level - I'm just concerned 
about after I hitch up.

Thanks,
Tom
