I have searched and reas a number of posts reguarding washing and waxing your RV, everything from Blue Dawn to Protectall and Meguires #56 RV and boat wax, etc.
I was at an RV Dealer and was asking about what they use. They said it would take the large kit to do a 3400RL which cost 149.95
Here is the site on the product they use, has anyone tried this
