Sorry if this has been covered before, Just wanted to get a sense of recommendation for storing/parking TT when not in use. I'm going to be keeping it on my property. The area where I have designated is mostly dirt right now, some grass but not where the wheels will be. I read that rvs should preferably be stored on concrete, asphalt or stone when not in use as a means of minimizing undercarriage exposure to dampness. I would prefer to not put in any of the options listed but will if I have to. Does parking/storing on this type of surface really make that big of a difference? What about any kind of weather sealer to apply to the undercarriage, anything like that available?
