She's an hour away?
I don't know exactly what your intentions are, but a girl an hour away is going to be good for one of two things: A girl that comes to you for sex occasionally/as much as possible, or a steady girlfriend you constantly drive an hour out of your way to.
Either way, it can easily be a huge waste of time. She's an hour away. My rule is that if a girl is any significant period of time away (i.e. it wouldn't be feasible for me to visit her place after work), then she is a waste of my time unless she drives to me. Only after a solid sexual relationship is established will I drive to her. Otherwise I am completely and totally wasting my time; what if I drive out of my way and I fail at closing? Wasted my time.
So what I would do:
Keep doing what you're doing. Text her, keep building the rapport. Get sexual through text/over the phone, but make it HER fault (this can only be done after you have a solid rapport). Example:
YOU: "I have so much experience, blah blah blah experience, blah blah blah experience experience" (in reference to your dating life).
HER: "Oh My God why are you telling me how much sexual experience you have?" (or something similar)
YOU: "Sexual? Dude I was talking about my life. Get your mind out of the gutter ya lil perv!!"
HER: "OH! HAHA! Yeah I am kind of a little perv actually. . ."
YOU: I'll bet you are. How so?
HER: "Haha I just am!"
YOU: "PROVE IT!"
HER: Sends you a picture.
Another example:
HER: I'm taking a bath!
YOU: PROVE IT!
HER: How so?
YOU: Be creative, dork.
HER: Picture of her legs
YOU: Damn cutie trying to get me to imagine what else is there? Ya lil perv!"
HER: Haha yeah I can be a bit of a perv!!
YOU: I'll bet you are.
ANYTHING where you can get a sexual conversation that SHE started, you're in. Once you're in, get her to owe you something. I don't care how you do it, just get her to owe you something. Say she "insults" you in some childish way you decide, then say something like "hah! yeah you fuckin' owe me BIG TIME for that one!!!" She should be receptive and say "Oh, I'll pay you back, don't worry." You can push a LITTLE further by saying "Yeah? How are you going to do that?". She'll say something like "you'll see". Leave it here, and set up a time for her to come over and spend the night as soon as possible.
Girls that are a distance away, if you build rapport over the phone, you can easily get them to agree to a sleepover as long as you have some other activity planned. One girl I did this same scenario with was a bigtime video gamer. I don't like video games, but I know enough about them to talk SOME lingo. So I played dumb and acted interested in her video gaming. I made her "owe" me "big time" for something I perceived as an "insult." She promised to "pay me." Sexual overtones were established, she said she was a perv, and I didn't push much further. I would say "i'll bet!" and then move on to what game she was going to have me play.
What happened? She shows up with a suitcase with her video game system. We watch a movie, as I assured her we would. Twenty minutes into the movie we were fucking, in other words: She made the "insult" up to me and "proved' she's a "lil perv."
What did we do after? Played video games. I'm a man of my word.
I've used this type of scenario several times for out of town girls. Build phone rapport, get her to say something sexual (usually accusing you of being sexual), you call her out ("get your mind out of the gutter! ya lil perv!

") She admits it, you confirm that you are pleased, you move on to non sexual talk. Go back to sexual talk, go back to normal talk.
Some girls get WAY sexual. Good thing, but not always. It's a trap sometimes. The trap isn't either of our faults. If you get insanely sexual with a girl over the phone/text, there is a potential that you will ruin the mystery that is you. Your job is to assure her you know what you are doing through anecdotes, rants, sexual philosophy, etc. Rarely do I explain what I do directly. I will give the girl a few key details about me sexually, other than that I stay away from ruining the surprise. Keep her wondering. Types of key details I give: "Some guys like to say how big they are. My cock is exactly average, no more no less, I don't lie about that shit. I'm comfortable with my cock. I mean, a lot of guys think it's all about size. Bullshit, it's all about what you do with that fucker!" She WILL agree, trust me. Further: "haha you know what though, for real, my cock is pretty. I mean, like, a dick is a dick, they all basically look the same. But you know how every once in a while there's just that really nice looking cock? Yeah I have a pretty polly!" (I actually do). They will laugh and say something affirmative.
If the girl gets insanely sexual, throw her a bone by giving her some hardcore dirty talk (if on the phone, speak slowly , sexually, very cheesy, and just generally "phone sex" her, tell her what you want to do. Do this for a minute, then stop. If texting it, send her a nice paragraph of how you are going to tease her pussy for ten minutes before touching her clit. Words like dripping wet, throbbing, pulsating, etc are fantastic. Don't do too much more than this.
If your plan is to drink with a girl, if she says you're going to have drinks. I always say "cool sounds good, just as long as you keep your hands off mah goods!". Almost every time she will say something like "Hah I can't promise that!!!" To which your response should be something like "Uh huh we'll see!! I'm not that easy!" Point here is to reverse stereotypical rules. She's the horny guy, you're the reserved girl.
After getting the girl over, I'll let her come back to me a few more times to spend the night. Once I get a SOLID sexual relationship going, I will go out of my way to visit her, and spend the night at her place.
The trap: Sometimes these girls will start talking about getting a place in your town. Thinking about getting an apartment there, etc, etc. Don't shoot it down, but don't be ecstatic about it either. My standard response: "yeah? That would be kinda cool." Unless you want a serious relationship, don't support it too much, it's fucking mean to drag a girl on like that, making her think she can have you.
You say this girl is a 10/10 for you, so maybe she's what you want to settle down with. Form your game around that. But I highly suggest you get it sexual as soon as possible, fuck the living shit out of her a few times so you can turn her into a human being in your head, and then move on to your actual goal: A relationship with a solid 10.
