Power levelers question

Well I may be in the minority, but my BIL has a class A and he has to manually level his. My class B+ has them and if ya just push the button, yes they will activate and all, but level?? I now just manually level the rig using them. As to just hit a button well I guess if you are on concrete pad it might work, but if on soft soil, or on tarmac when its hot all that may also change. The pads are not that big on a cl c and they will sink into the dirt if there is not some other firm support. Just like with a TT or 5th wheel. Weight is weight and it has to have some support sometimes. I have also parked on inclines and if we didnt have some boards to block with we would be SOL! Yes they are nice but not the panacea some suggest. There is still work to make them work right. My rear legs will lift the rear wheels and make it off kilter F-R, front legs just do not deploy like the rears. These BTW were factory installs. Just read up and see the items that CW sells for putting under the levelers, the magazines also have conducted some tests using the pad support to see which worked the best, and yes they stressed the problems on soft dirt and asphalt/tarmac when its hot.
