Hello forum

I am new and this is my first forum post. My wife and I are thinking of packing it all in and going on a global tour, first from Florida (where I am) to Alaska. After there, we have a real urge to visit Australia and New Zealand. From there, who knows..

There is a problem.. I guess there always is.

My first concern is that we have a stable income of around $1500 a month to go on. We have retired young, I am 38, she is 39. I'm thinking that is enough to go if we plan on spending some time stealth camping.. which we both absolutely love to do. I'm wondering if anyone had some advice on whether or not that sounds like a good budget for a couple who plan on living a bit frugally? I do want to see the sights, but we aren't the type to want to spend each night in a motel.

The next, and biggest concern I have is I have back trouble. While I am able to deal with 'the stretch' to the handlebars for day trips, I'm pretty sore when I'm done. I would very much like some reccomendations on a bike that is suitable for long distance touring but also provides a more upright position. I don't see myself being able to enjoy the ride if I'm leaned over reaching for the handle bars for days on end. I realize that I'll increase my wind resistance, but that is of little concern to me since we won't be trying to break any land speed records and it'll be all about the scenery, the cultures, and about taking it all in.

So.. I'm looking for a little advice..

I want to go the long distance, but I need to sit upright and comfortable to do it. I don't want to go the recumbent route since it just doesn't suit the 'spirit' of it all to me for some reason. I'm comfortable on a bike, I just want one that leads a little to my needs.
