setting out landing gear while still hooked up to truck

I do it all the time for one night stays. While I do not have a six point leveling system, I do have auto level capability. Yes it does take some weight off the TV, but it does not "hang" the truck, in the AM it is "auto retract all" push of a button and we are off to our next destination. I guess it depends on the system weather to unhook or not!
