Leaving slide partially open?

Leaving for a week long trip to Rushmore tomorrow. My TT has 3 slides, two of them when closed restrict access to the fridge and rear of the rv.

Any problems opening both just a foot for some walk around space and leaving them overnight?

Driveway is sloped, but now that excitement has kicked full in, i want to start loading dry goods, have a beer and put the radio on....

Im always paranoid about slide durability...
