A couple of tools for your travels.
Weatherbase. It won't tell you the weather when you go, but it will tell you what the past weather has been, by city within state, by month, over the last several years, so you'll know what to pack and maybe what to avoid when you're going to travel.
And
RV Park Reviews. . It will tell you what RV parks are nearby and includes the amenities, such as water, sewer and/or electric, cable and WIFI, and a recent price. It may not include all of the CGs in the area - only the ones that folks like us have reviewed. It usually lists a phone number as well. Both are free.
