Snow Birding in Phoenix

I am not sure if this is where I should post my question. So if it's the wrong place tell me. We are planning on snow birding in Phoenix AZ for 3-4 months Jan-March or April. I know we should be thinking about making reservations now so we have a spot. Have you any recommendations for campgrounds or rv parks in Phoenix. We have traveled there before but never in the MH. Any insights, tips or recommendations would be greatly appreciated.

Thanks and we will see you in Goshen!:)
