Towing a van with D4 - unhitch at night?

I quite often leave the van hooked up over night, we don't use any legs. We like to level it up so show water runs out ok. Here we are at Jame Earl Lookout, south of Lakefield I think. It is a bit of a slope down, I have a piece of wood each side under the rear wheels, D4 at off road and LLAMS at +50. I originally took this to tell Graeme about new use for LLAMS but have never posted it until now.
I adjust the D4 to what ever is needed to get van level and don't every remember it not being the same in the morning.

Have I read somewhere that special programs wont change the height automatically if trailer is attached? Maybe the trailer being detected also stops the leveling. Anyway I reckon the water runs out the show the same next morning. You can see the picture was taken next morning.

I'm in the process of fitting 17" X5 wheels to my small van which will give it another 2" lift after having just replaced the suspension with a good off-road setup. Even though I've lowered the coupling 3" and will get a 2" raised hitch, it will still need to be levelled at night so Llams will be put to use there too - just have to get the right combination each time. Better to have the van a little nose down to prevent the tail from getting too low if the vehicle needs to be raised for obstacles.

I tow a 3.5t van and if I am free camping for the night I am usually too tired to worry about the cars suspension and don't put the stabilizer legs down on the van. I go to sleep. There are more things to consider/ponder than two inches up or down....I stay hitched because you just never know if you have to pack up real quick..
