I would have to go back an read my owners manual on the " checks level every half hour" mine has never done that.i use the automatic function to level it and then fine tune it, it has both modes,i have never had a problem with them bleeding off, they use the plastic hydraulic hoses and are a one size fits all so I had to lay them out under the coach to find the best fit, all 4 hoses are different length,
