First off, a belated welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are
here.
I used the Lynx levelers (that Dennis recommends) for both our former Class C and our current Class A. They are sturdy, lightweight, and don't rot. We have three sets, plus 3 extras, and I've used them all more than once. I also have found the Lynx caps and chocks useful (for example, the chocks help you to stop before you overrun the stack of levelers).
I have also found it helpful to have some "pads" to go under the blocks when the ground is soft.
