Full Disclosure-Total Newbie! Starting "the Plan" :)

Smart approach and I am sure you will get some good advice. Too many of us trade our way, at considerable expense, into something that works for us. My first comment will be that you do not have to back a Class A into a site with the car attached. In fact, that is almost impossible. One unhooks the car which makes parking the motorhome easier than a trailer since there is only one vehicle to back in.
