I assume you are talking about when parked and you do not want to unhook. You should have levels reflecting the rig level when unhooked, and have your hitch adjustments such that the rig and tow vehicle are as level as possible when hitched up. In most instances that should make you ok on a site. If you need to raise the fiver to be level which I have found to be the normal situation, you can simply release the king pin, raise until level, leave the truck in place, drop back down when you get ready to leave.
