We take along a set of tri-level blocks. It only takes an extra 1 to 2 minutes to take them out of the storage compartment, lay them down on the ground, and then drive up on them. These do not cost very much at all, but more importantly, will never break down. One cannot say that about a leveling system. Also, one does not need to get wet to deploy them when it is raining. If it is raining, you can wear a raincoat, or just wait until the rain stops. Just like when you do the hookups when it is raining.
That being said, I will also say that we only use them in about 25% of the campsites we visit (always state parks). If we did commercial campsite, we would probably need them even less.
