This is a big subject, and I have edited down my original post on this topic.
I don't wish to discourage anyone's dreams, but imaging in itself is a big learning curve if your coming off a zero base. I would suggest you give yourself time to learn before you hit the road.
Then think carefully about what you take with you and be realistic about what you can do with it. Aim for simplistic setups that meet your objectives, and if imaging go for fast optics and recognise that darkness is required (and that can mean sacrificing being close to amenities and comforts of the big parks). Be experienced in setting up and aligning an EQ mount. Know how to guide the setup and have all the bugs worked out at home.
Think carefully about your scope choice, and storage, as most don't take kindly to being pounded by corrugations. Having it on the back seat of your vehicle is always better than in a caravan storage.
