How level is level?

[MrEvolution]

I have a steep driveway and I have it parked the way I want. I lifted the front end to level it with blocks. I'm still about 2-3 inches from level. Is this level enough for the fridge to plug it in?

I believe the fridges can tolerate up to 6 degrees out of level. If it's that far out of level, you'd notice it far sooner than the fridge, so you should be okay, just as long as the fridge isn't being run for long periods of time.

With a pop-up, I'd be more worried about the lift system binding because it's out of level. Although I haven't had a pop-up in over ten years, maybe lift systems have improved since then.
